Technical data


High performance cooling unit for vertical installation. CUON is the air conditioning solution for critical environments, when the air conditioner is installed outdoors. The unit is external mounted in order to maximize space inside the enclosure. Common to all models is the self cleaning condenser coil, which eliminates the necessity for an air filter, avoiding standard maintenance. The thermostat is inside the unit and is adjustable between 25 °C and 45 °C with the Electronic Key-Pad (CUK01), which is available as an accessory. The factory setting is 35 °C. The cooling unit can also be supplied with a mechanically adjustable thermostat upon request. Ozone friendly refrigerant R134a.

Outdoor vertical cooling unit with smart energy management, available in a wide range of sizes for different cooling capacities, with a IP 54 protection degree.


Customers can choose the cooling unit that meets their requirements the most, removing any extra costs due to oversizing. Smart energy management reduces the cooling units energy consumption by up to 23%.


The efficient cooling unit allows customers to optimise the enclosure's design ensuring that the correct cooling unit is chosen and it hasn't been over specified. The smart energy management and ease of installation will reduce both operational and installation costs. Stainless steel outdoor cooling units are available for harsh environments.


To minimise how much energy the cooling unit consumes, it is recommended to install the door switch, DSW01. Once installed, the door switch will turn the cooling unit off, once the door is opened.
