Walk-In Cool Rooms, Freezer Rooms and Production Rooms
With over 30 years of experience and more than 6,000 installations across New Zealand and the Pacific Islands, Honar Refrigeration engineers complete cool room and freezer room solutions for commercial businesses. We handle the full process from consultation and specification through to supply, installation, and ongoing service, with a nationwide network.
Why Businesses Choose Our Modular Cool Rooms
Our systems are built using MISA modular camlock polyurethane panels from Italy, trusted by some of the country's biggest food and beverage operators. The MISA modular system is designed for easy assembly and disassembly, meaning your room can be expanded, reconfigured, or relocated as your business grows. It's suitable for cool rooms, freezer rooms, production rooms, processing plants, and any food-grade environment.
MISA panels offer significant advantages over traditional expanded polystyrene (EPS) construction:
Patented technology
MSV (Misa Vacuum System) provides excellent insulation properties to reduce power costs.
ISO 9001 Certified Quality System
Misa cool and freezer rooms comply with the Australian and New Zealand building code, the Australian Food Safety Standard 3.2.3 (food premises and equipment) and the Australian Standard AS4674-2004.
Superior insulation & Energy Efficient
High-density polyurethane with patented vacuum-injected construction. Up to 50% more energy efficient than EPS, and panels hold no moisture, maintaining insulation performance long-term.
Fast installation
Patented 'Fast Fit' twin hook camlock system. Assembled with an allen key in hours, not days. No cutting, riveting, or gluing on-site. Eliminating any Health & Safety Concerns.
Fire retardant
HFC & CFC free, environmentally friendly, self-extinguishing foam exceeds standard EPS fire ratings. Can result in lower insurance premiums.
Food-grade finish
Plastic powder-coated anti-bacterial panels with rounded internal corners are easy to clean and surpass health department sanitation requirements.
Expandable & relocatable
Your MISA room can be easily expanded or relocated as your business grows. Panels can be added or taken out easily at a later date, enabling flexibility and efficiencies compared to other systems. Chiller, freezer, and production rooms can be configured side-by-side as a single modular system, sharing walls and saving space without compromising temperature separation.
Thinner panels, more usable space
Same insulation value in a panel up to 50% thinner than polystyrene, giving you more room inside. Assembled from the inside out, so every millimetre of available space is used, ideal for tight or awkward sites or high rises.
Flat-packed nationwide delivery
Panels ship flat, keeping freight costs low regardless of your location. No oversized trucks or crane access required on-site.
Retains more resale value
Thanks to its flexibility and easy relocation, the MISA modular system helps your investment keep more value than most other panel systems.
Cool Room Solutions by Industry
Our cool rooms and freezer rooms are built for commercial environments where reliable temperature control and cold storage are essential.
Supermarkets & Dairies
Large-format cold storage behind the shop floor. Multiple temperature zones for chilled and frozen stock, with configurations designed for high-turnover restocking.
Hospitality & Cafés
Compact walk-in chillers for daily prep storage. Ideal when you've outgrown underbench and upright fridges and freezers. Our smallest configuration starts at just 950mm x 1350mm and increases in 400mm increments to suit all size requirements.
Restaurants & Commercial Kitchens
Dual-purpose setups with a chiller for fresh ingredients and a freezer room for bulk stock, connected and accessible from your kitchen workflow. Production rooms for large-scale prep are also available.
Butcheries & Meat Processing
Walk-in chiller and freezer rooms for meat ageing, storage, and processing with heavy-duty insulated floors, meat rail options, and temperatures maintained at 0°C to -25°C.
Blast Chillers and Freezers
Using rapid-cooling technology, our units chill product to +3°C in under 90 minutes, minimising moisture loss and preventing bacterial growth without compromising texture or taste. The range spans compact benchtop models through to larger-capacity units, suited to prep kitchens, catering operations, and production sites alike. They're a staple in hospitality, catering, and food manufacturing environments where teams need to batch-cook, cut prep time, and extend shelf life on high-value or time-sensitive ingredients, and in supermarkets and ready-meal operations, they're key to safe storage of high-turnover chilled and frozen stock.
Bakeries
Temperature-controlled production rooms and prover rooms for dough management, alongside freezer storage for finished goods. The modular system allows precise temperature zoning across different stages of production.
Food Manufacturing & Processing
Large-format freezer and production rooms for processing plants. Remote condensing units support high-capacity environments where ambient heat from the compressor needs to be managed away from the workspace.
Beverage & Liquor
Walk-in bottle stores and keg rooms with stable chiller temperatures. Sized to suit anything from a single bar's keg storage through to large-format distribution cold stores.
Cool Room Sizes & Configurations
MISA rooms are available in over 200 size configurations across chiller and freezer configurations, with or without floors. Not sure what size you need? We'll spec it based on your product volume, space, and workflow.
Misa Panel & Door Specifications
Panel System
MISA panels are supplied in two thicknesses: 60mm (S6) for chiller rooms and 100mm (S10) for freezer rooms. Rooms are available in 2030mm or 2430mm internal heights, with custom sizing in 400mm increments. All rooms come standard with a 700mm hinged door.
Floor Panels
Floor panels are made from high density reinforced polyurethane panels, featuring a completed floor surface with an anti-slip plastic coating. No vinyl required.
If a level, flat concrete slab exists at ground level, a cool room can be built directly onto it without a need for MISA floor panels. Rooms without floor panels use a coved high density plastic 'U' channel secured to the existing concrete floor, enabling a fully sealed finish and integrated cove detail. Being made of high density plastic enables no heat transfer/ sweating.
Doors
MISA rooms are available with hinged doors (700mm or 1000mm), sliding doors (800mm, 1000mm, or 1600mm), and Reach-In doors (full or split, 610mm). Hinged doors include a key lock, luminous internal safety release, illuminated handles, and heavy-duty plastic hardware. Chiller and Freezer doors add a heated frame and pressure relief valve to prevent blow-open on defrost cycle.
Additional access options include:
- Windows
- Swing doors
- Strip curtains
- Metal rails/hooks
Glass door inserts
Toughened, double-glazed viewing panels set into a solid door (or wall panel) so staff and customers can see stock without opening the door. Reduces cold-air loss from frequent door opening and helps with merchandising in retail-facing chillers; a heated element is fitted to prevent fogging on freezer applications.

Refrigeration Equipment
Misa industrial chiller and freezer rooms can be equipped with Monoblock (integral) or remote condensing units.
Monoblock (Integral)
A plug-in or drop-in condensing unit can be utilised on any room, not only Misa. No refrigeration engineer or electrician is needed and it is operational in minutes. The Monoblock comes with a hermetic compressor, air condenser, suitable for ambient temperatures from 0°C to 43°C, digital controller, light and dissipation tray, so no need for separate plumbing.
Best for: any situation where there is space to fit with adequate ventilation.
Remote Condensing Unit
A traditional separate system that allows the condensing unit to be installed separately, away from the room. It includes a condensing unit with a hermetic compressor, an air condenser suitable for ambient temperatures up to +43°C, a digital controller and a light.
Best for: larger rooms, multi-room setups, or noise and heat-sensitive environments.
Not Quite Ready for a Walk-In?
MISA produces modular Reach In rooms, supplied with or without Monoblock cassette motors for customers who need a storage solution bigger than a freestanding plug-in fridge or freezer but smaller than a full coolroom or freezer room. These units are available in an 830mm internal depth, or wider in increments of just 400mm. Warehouses, bakeries, caterers, pharmaceutical suppliers, and rest homes have all benefited from this design. Available options, on request, include shelving, glass doors, split doors, and full-height solid doors with or without viewing windows.

Frequently Asked Questions
What Is a Cool Room?
A cool room is a temperature-controlled space used to store perishable goods at consistent temperatures, typically between 0°C and 5°C. A freezer room operates at -18°C or below. Unlike standard commercial fridges and freezers, cool rooms offer the capacity and accessibility needed for businesses handling large volumes of stock daily.
How much does a walk-in cool room cost in NZ?
Cost depends on the size, configuration, whether you need floor panels, and the type of refrigeration unit. Please contact us for a free, no-obligation quote based on your specific requirements.
Do I need building consent for a cool room?
In most cases, a modular cool room installed inside an existing commercial building does not require building consent, as it's classified as a fitting or chattel rather than a permanent structure. However, requirements vary by council and situation (e.g. if electrical or plumbing work is involved).
How long does it take to install a walk-in cool room?
MISA modular rooms can be assembled in hours, not days. The 'Fast Fit' camlock system means panels lock together with an allen key, no cutting, riveting, or gluing. Total project time including delivery, assembly, and commissioning is typically 1–3 days depending on size and complexity.
What are the running costs?
Running costs depend on room size, insulation thickness, ambient temperature, door opening frequency, and the refrigeration unit fitted. MISA polyurethane panels are up to 50% more energy efficient than polystyrene, which directly reduces power consumption. We can estimate running costs as part of the quoting process.
How do I maintain a cool room?
Regular maintenance includes checking door seals, cleaning condenser coils, monitoring temperature consistency, and ensuring drainage is clear. Honar Refrigeration offers ongoing service contracts to handle scheduled maintenance and keep your system running efficiently year-round.
Do you provide cold room installation nationwide?
