Frequently Asked Questions
What are the requirements to build a cold room or freezer room?
Cold rooms and freezer rooms are built inside warehouses, factories, shops, containers and houses. You’ll need at least a level concrete floor to install on and a canopy over the entire unit to keep it from direct sun and elements and sufficient electricity.
What is a cold room
A Cold room (+1°C to 101°C ) or Freezer ( -15°C to -30°C) room is an insulated and refrigerated space that is temperature controlled to aid in the preserving products that require cold temperatures. Specialized cold rooms and freezer rooms for specific products require specific temperatures to preserve the product better, Like for instance vegetables require 5°C and blast freezer -35°C.
How many days does it take to build a cold room or freezer room?
This depends on the size of the cold or freezer room and accessories involved. (As example a simple 9m x 9m room can easily be completed in +-3 days)
What info do I have to give when I ask for a quote ?
Each room is custom designed to suit the application of the specific customer. The following aspects are considered when designing the room: 1) What size room do you need? (length x width x height) (dependant on space you have available and volume of product you would like to store.) 2) What product is stored in the cold or freezer room? 3) Volume of product entering daily? (In Kg) 4) Total volume to be stored? (In Kg) 5) Temperature at which product will be entering? (degrees Celsius) 6) Temperature required? (std +1 °C for cold rooms and -20°C for freezer rooms) 7) Time required to get product down to required temperature? (Pull down time of product, standard is 24hrs) 8) Door size required? (Std hinge- 900 x 2000mm. Std slide- 2400 x 2400)(any other size required) 9) Location of installation. (Country and city).
What is the most popular size of cold room?
On the small range: 2.4mx 2.4m or 3.6m x 2.4m or 3.6m x 3.6m or 4.8m x 3.6m or 4.8m x 4.8m On the larger range: These can be custom built to any size required.
Where should we place the condensing unit?
The condensing unit is placed outside, connected to the internal evaporator blower coil with copper tubing and wiring.
How much noise does the freezer unit make?
This will depend on the size of the compressor or condensing unit. Africhill uses modern packs enclosed units with silent scroll type compressors.
Will there be any noise and dirt involved during the installing?
All rooms are pre manufactured and flat packed in our factory to allow ease of installation on site with a minimum cutting and modification needed on site. Installations are clean and quick.
What are the building phases of a cold room?
Our teams will start with the construction of the insulated structure first. Once the main structure is standing another team will start installing the refrigeration equipment while the first continues with trimmings and finishing of the insulated structure until full commissioning of system.
How will delivery of the cold room to my premises take place?
The cold room will be delivered as a flat packed modular system that will be moved into the required space as pre-manufactured pieces and assembled inside the required area.
Can you control the cold or freezer room based on the storage temperature I choose?
Yes, we can design the cold and freezer room to operate at your required temperature.
What electrical connection do I need to use the cold room?
Refrigeration units require 1Phase 220V or 3Phase 380V systems. Typical domestic units will run off a 1Phase supply. Any system larger than a 2HP will need a 3Phase 380V supply. We will specify the amp required for each system.
How long does the cold room or freezer room take to cool down?
This can be customized and designed to suit your requirement and application. We will consider the product heat load, quantity, weight and required cool down time when calculating the cooling capacity requirement of the cold room or freezer room.
Do the cold room stop working on very hot days or in hot climates?
Certainly not if the cold room is designed correctly. Our units are designed to operate in the harshest African ambient and will on hot days continue to cool and preserve your product!
