DUCTABLE AIR-COOLED SCROLL CHILLERS 30PA / PAC
Casing - Casing made of galvanised steel metal with polyester paint, colour RAL 7035. Self-supporting and isolated frame. Outdoor circuit - Coil with copper pipes and aluminium ﬁns. - Condensate drain pan. - Choice of air supply position: • HORIZONTAL: M00 assembly or VERTICAL: M01 assembly.
Supply fan: STD Version (Standard): • Centrifugal fan coupling by pulleys and belts. • Electric motor with tensioner, energy-efﬁcient IE2 motors, class F, IP55, and internal thermal protection. • One double-intake turbine, with an impeller with front-curved blades. Greased spherical bearings, with no maintenance required. • Choice of available pressure from 7 to 35 mm.w.c.
• Variable speed electronic plug-fan(s) with condensation pressure control which adapt their rotation speed to the installation requirements, thereby reducing electricity consumption, the sound level at partial charge, and improving the average seasonal output of the unit (ESEER). • Energy-efﬁcient ErP 2015 motor, Class F, IP54, and internal thermal protection. Cooling circuit - Hermetic scroll-type compressor, with acoustic insulating cover, assembled over antivibration mounts. Control of phase equilibrium and the direction of rotation. - Crankcase heater. - Thermostatic expansion valve with external equalisation. - Anti-acid dehydrating ﬁlter, and liquid sight glass. - Liquid receiver (heat pump units). - Four-way cycle reversing valves (heat pump units). Indoor circuit - Thermally isolated, welded stainless steel plate exchanger.

Protections - High and low pressure pressostats. - Differential pressure switch for control of water ﬂow. - Water anti-freeze protection built into the control, depending on the temperature measured by the probe placed on the exchanger outlet. - Refrigerant anti-freeze protection. - Compressor discharge temperature control. - Non-return valve built into the compressor discharge. - Compressor thermal protection. - Main door switch. - Automatic switch in the control circuit. - Magnetothermic protection switches for the compressor and fan motor power line. - Timing the disconnection of the circulation pump. - Failure safety device for the circulation pump. Electric panel - Complete and fully wired electric panel. Insulated panel cover to prevent condensation. - IP55 protection. - Power supply with neutral and main ground connection. - Compressor and fan motor contacts.
Version with circulation pump included (30PAC) This version includes, in the same casing that the 30PA version, the following components: - Monocellular IP55 centrifugal circulation pump that can operate with glycol water (mono-ethylene glycol). The pump must be changed for mono-propylene glycol (upon request). - Closed expansion vessel. - Safety valve with a tare value of 4 bar and draining valve. - Air bleeder valve (model 160HEE and 180HEE). - Filter with stainless steel mesh (500 microns), supplied in the kit for installation by the installer.
