The machines are made with weather resistant materials and suitable for outdoor installation. 
Framework with sections of thick steel for high resistance to the greatest stress during handling and transport. 
Machines supply fully assembled with refrigerant charge and control systems. The installation requires electrical and hydraulic connections only allowing high costs and time reduction. 
Final assembly on all machines before shipment including running test, reading and monitoring of operating parameters, alarms simulation and visual check

Free Cooling Chiller are available in  :

GLIDER EVO FREE CLA “F” – Free-cooling chiller in “A” class energy efficiency (*)

Free-cooling capacity 312 ÷ 1339 kW

 

FRAMEWORK 

Base, self supporting frame and panelling in steel plate with protective surfaces treatment in compliance with UNI ISO 9227/ASTMB117 and ISO 7253, and painted with epoxy powders. 
Compressors compartment. 
Colour: RAL 9002 

COMPRESSORS 
  • Orbiting spiral (SCROLL) hermetic compressors with spiral profile optimized for R410A refrigerant. 
  • ON / OFF capacity control (0 / 100% each compressor). 
  • 2-pole 3-phase electric motor with direct on line starting. 
  • Phase sequence electronic relay. 
  • Crankcase heater. 
  • Electric motor thermal protection via internal winding temperature sensors. 
  • Rubber supports. 
  •  

EVAPORATOR 
Copper brazed plate type with cover plates, plates and connections in AISI 316 stainless steel: 

  • With single refrigerant circuit for S version machines. 
  • With double refrigerant circuit for D version machines. 
  • Anticondensate insulation made of polyurethane. 
  • Temperature sensors on water inlet and outlet. 
  • Water flow safety switch. 
  • Antifreeze heater. 

 

CONDENSING COIL 
Heat exchanger coil with internally corrugated copper tubes and high efficiency aluminium fins, specifically developed to provide high heat transfer and lower pressure drops. The combination of two factors, special tubes and fins, allow to optimally combine the following aspects: 
- Maximum capacity relative to the size of the exchanger. 
- Minimum charge of refrigerant. 
- Reduction of the air flow required for the heat exchange. 
Sub-cooling circuit to allow a significant increase in cooling capacity. 
Frame in galvanized steel. 

FREE-COOLING COIL 
Heat exchanger coil with copper tubes and high efficiency aluminium fins, specifically developed to provide high heat transfer and lower pressure drops. The combination of two factors, special tubes and fins, allow to optimally combine the following aspects: 
- Maximum capacity relative to the size of the exchanger. 
- Reduction of the air flow required for the heat exchange. 
Frame in galvanized steel. 
Motorized valves for free-cooling water circuit control. 
Temperature sensor on ambient air. 
FANS SECTION 
Axial fans with sickle-shaped blades, fan guard and optimized for low noise levels. 
External rotor electric motor with stepless variable speed for condensing pressure control. 
IP54 enclosure class. 
REFRIGERANT CIRCUIT 
Components for each refrigerant circuit: 
  • Electronic expansion valve. The valve allows high performance and system efficiency thanks to a timely and accurate response to changes in temperature and pressure. 
  • The expansion valve is equipped with energy reserve to allow the closure of the valve in the event of lack of power supply. 
  • Sight glass. 
  • Filter dryer on liquid line. 
  • Service valves on liquid line and gas discharge. 
  • Liquid receiver with safety valve. 
  • Safety valve on low pressure side. 
  • Pressure transducers with indication, control and protection functions, on low and high refrigerant pressure. 
  • High pressure safety switch with manual reset. 
  • Refrigerant circuit with copper tubing with anticondensate insulation of the suction line. 
  • Plastic capillary hoses for pressure sensors connection. 
  • R410A refrigerant charge. 

ELECTRICAL PANEL 
In accordance with EN60204-1 norms, suitable for outdoor installation, complete with: 

  • Main switch with door lock safety. 
  • Magnetothermic switch or fuses for each compressor. 
  • Magnetothermic switches for fans or water pumps (if scheduled). 
  • Contactors for each load. 
  • Transformer for auxiliary circuit and microprocessor supply. 
  • Panel with machine controls. 
  • Power supply 400/3/50.
