CIATCooler LP
Protections
High pressure switch. Low pressure safety device integrated into the control. Water flow controller. Water anti-freeze protection built into the control, depending on the temperature measured by the probe placed on the exchanger outlet. Water anti-freeze thermostat as additional safety. Control of the compressor discharge temperature. Check valve integrated into the compressor discharge. Compressor heat protection. Main switch. Automatic control circuit switch. Thermal-magnetic protection for the compressor and fan motor supply line(s). Time delay for circulation pump stop. Circulation pump failsafe.
Hydraulic module
LPC/ILPC versions can be equipped with a hydraulic module. This includes a thermal buffer tank, made from black steel sheet
LPC / ILPC Hydraulic module
Electrics box
Complete electrics box, fully wired and insulated to prevent condensation. IP55 protection. Power supply with neutral and main earth connection. Compressor and fan motor assembly switches.
Buffer tank
This version includes the following elements, on the same frame as the LP/ ILP version: Single-cell centrifugal circulation pump, IP55, which can run using glycol/water mix (monoethylene glycol). For monopropylene glycol, the pump will have to be changed (please consult us). Note: Models 420 to 720 incorporate two pumps which operate simultaneously (acting as a single pump). Enclosed expansion vessel. Safety valve (4 bar rating) and drain valve. Air bleed valve (on models 200 to 960). Stainless steel screen filter (500-micron), supplied as a kit to be installed by the customer.
Version with circulation pump included (LPC / ILPC)
LPC / ILPC
metal, painted and heat-insulated, with a 1kW electrical heater for antifreeze protection. This heater, in heat pump models, has the option to be replaced by a support heater in 1 to 4-stage (3 to 48 kW according to the model). This hydraulic module can be supplied: Separate for connection on site by the installer. In this case, the flexible connections of 500 mm (option) are recommended. Coupled to the LPC / ILPC unit, models 90 to 360 (STD version) and models 90 to 280 (HEE version). Note: If the hydraulic module is delivered separately, the antifreeze protection (with electric heat trace cables) can only be guaranteed if the unit is directly connected to the module using threaded couplings (which must be insulated). Distance to be observed: 167 mm. For this reason, the antifreeze protection option with electric heat trace cables is not compatible with the flexible connections.
