Air temperature range:
A packaged ice machine will have an operating air temperature range, typically 5ºC to 40ºC for standard UK specification models and 5ºC to 45ºC for tropical specification models.
Low temperature environments
If considering an air cooled model and the air temperature in the room where the machine is to be installed may go lower than 5ºC, then to avoid freezing air being sucked through the machine a remote option should be chosen and a frostguard heater fitted inside the machine to prevent freeze up. This is easier with the models that are housed in frame and panels, although a cover could be fitted to unhoused models.
Water cooled machines have the same operating temperature ranges, however additional insulation and frostguard heater would be sufficient in most cases.
For applications where the temperature would be permanently low, then a cold temperature pack should also be selected for both water and air-cooled machines.
Standard ice machines are designed to be installed indoors. For outdoor installation, a remote condenser, frostguard and extra insulation must be used. The machine must also be protected from rain by a roof or cover. Contact us for advice.
Warm temperature environments
Standard UK specification models have outputs stated at 20ºC and tropical models at 35ºC. Every degree above these tempeatures and you will lose around 1.5% of ice production.
For this reason, when the machine is to be installed into an enviroment that may become warmer than 30ºC for standard UK specification models or 40ºC for tropical models then we would usually recommend that a remote model is chosen to remove the condenser to a better location with a more sensible temperature.
If a remote machine is not possible, then water cooling would be the only option.
