Cooling Systems

The Cooling Unit B.U. offers a wide range of customized cooling units. Every unit is the result of an engineering project which starts with the specification of the customer and ends with the qualification of the final prototype.

COOLTECH do not offer a catalogue of standard units. We have a strong know-how in the field of liquid cooling and every unit is designed to offer the best performances and reliability.

Our engineering team can develop from simple subassembly for OEMs to complete PLC controlled cooling solutions. Our cooling units are all conform to CE and, upon request, can be UL certified as well as other norms.

Our product topology consists in three different families of cooling units.

ALS : Air to Liquid cooling units up to 100kW

These units uses ambient air to cool down the liquid to be used for the process. Every unit consists of the following main components:

• Air to liquid heat exchanger made of aluminum, copper or Stainless steel, according to coolant compatibility.
• Fans: to blow air throw the heat exchanger.
• Reservoir, pressurized or pressure less according to design requirements.
• Pump available in many variants like Positive displacement (PD), centrifugal (CF), gear (GP) or turbine (TP).
• Control unit : from a simple connector to be connected to a main control unit to a complete PLC based solution connected via a communication line (Ethernet, RS485, Modbus etc…)
• ALS units can be made with different sensors and power supply options.

LLS : Liquid to Liquid cooling units up to 300kW

These units uses factory water to cool down the liquid to be used for the process. Every unit consists of the following main components:

• Liquid to liquid heat exchanger made of Stainless steel, according to coolant compatibility.
• Mixing valve : to regulate the temperature of the secondary water using a non-stable primary water temperature source.
• Reservoir, pressurized or pressure less according to design requirements.
• Pump available in many variants like Positive displacement (PD), centrifugal (CF), gear (GP) or turbine (TP).
• Control unit : from a simple connector to be connected to a main control unit to a complete PLC based solution connected via a communication line (Ethernet, RS485, Modbus etc…)
• LLS units can be made with different sensors and power supply options.

CCS : Compressor based cooling units up to 30kW

These units are normally known as “Chillers” and they use a refrigerant circuit with FREON gases to cool down the liquid below ambient temperature. Every unit consists of the following main components:

• Refrigeration unit, with R134a or R410a refrigerants. The refrigeration unit can use an AIR COOLED condenser or a LIQUID COOLED condenser according to customer’s needs.
• Reservoir, pressurized or pressure less according to design requirements.
• Pump available in many variants like Positive displacement (PD), centrifugal (CF), gear (GP) or turbine (TP).
• Control unit : from a simple connector to be connected to a main control unit to a complete PLC based solution connected via a communication line (Ethernet, RS485, Modbus etc…)
• CCS units can be made with different sensors and power supply options.

COOLTECH is focused on high tech chillers where reliability and efficiency are the key factors.
