Water chillers and air-to-water heat pumps
The pump installed on a LPC / ILPC unit can be replaced by: Single-cell, high operating pressure circulation pump, IP55, which can run using glycol/water mix (monoethylene glycol). Single-cell, low operating pressure circulation pump, (except on models 90 and 720), IP55, which can run using glycol/ water mix (monoethylene glycol). For units with a standard or high pressure pump: - Dual circulation pump, with automatic switchover of operation between the two pumps, controlled by a timer (on models 200 / 240 / 280 / 320 / 360 / 840 / 960). - Back-up pump: the hydraulic circuit has three built-in pumps, one of which is a backup. Using the manual 3-position switch, it is possible to select which two pumps will be operating (on models 420 / 480 / 600 / 640 / 720).
Compressor sound insulation jacket (LOW NOISE).
Auxiliary heater, in heat pump models, supplied in the hydraulic module (1- or 2-stage). Available capacities depending on the model: 3kW / 6kW / 8kW / 12kW / 24kW / 36kW / 48kW. Note: this heater is fitted in place of the antifreeze protection electrical heater (1kW) which is fitted as standard in the buffer tank.
Hot gas recovery circuit which includes: Plate heat exchanger in welded stainless steel, with heat insulation, to operate in a closed circuit to ensure recovery of hot gases. Drain valve and ball valve. Hot water recovery control thermostat. Optional three-speed hot water circulating pump.
Vertical supply air, M01 assembly (default option: horizontal supply air, M00 assembly). For the STD version: different operating pressure configurations from 7 to 35 mmWC (default option: 20 mmWC). For STD version machines running in refrigeration mode with an outdoor temperature below 12ºC, it will be necessary to control the condensation pressure using a motorised damper box. This option enables "all-season" operation down to -15°C.
Rubber anti-vibration mounts. Protective grille for the coil. Gravimetric filters on the return air. The filter frame is removable and can be supplied separately on request, to be fitted on-site. Flexible sleeves for supply air and return air. Flexible hydraulic connections (500 mm), supplied as a kit. Available for: - Unit inlet/outlet. - Hot gas recovery circuit inlet/outlet. - Connection between the machine and the self-contained hydraulic module. For LP / ILP units, stainless steel screen filter (500-micron), supplied as a kit. Note: this filter is delivered as standard with LPC / ILPC units. Water regulation and shut-off valves, supplied as a kit. High and low pressure gauges on the refrigerating circuit. Skids for container handling: models 420 to 960 (STD version) and models 320 to 720 (HEE version). Soft starter for the compressor. Transformer for power supply without neutral. Voltage: 400 / 440V - 60 Hz (please consult us). Energy meter for monitoring of the power consumption of the installation.
