Construction
The base is fabricated from galvanised steel to ensure a rigid, durable, weatherproof construction.
The superstructure is manufactured from galvanised sheet steel coated with epoxy baked powder paint to provide a
durable and weatherproof nish. Standard unit colour is Light Grey (RAL 7035).
Compressors and evaporator are mounted on a rigid galvanised heavy-duty sub frame.
Fully weatherproofed electrical panels are situated at one end of the unit.
Refrigeration
Compressor
Scroll compressors comprising:
● Internal motor protection
● Internal pressure relief
● Non return valve
● External discharge temperature protection
● Oil sight glass
Each Tandem / Trio set has an oil equalisation line.
The compressors are mounted to the rigid galvanised heavy duty sub-frame with the use of vibration reducing isolation.
Compressor Staging
The sequence of the compressor staging has been engineered to optimise the units ESEER performance.
Refrigeration Pipework Components
Sight Glass
A liquid line sight glass is tted to give an indication of the state of the refrigerant within the system. If the sight glass
becomes yellow it’s an indication that the lter drier requires changing.
Liquid Line Ball Valves
Liquid line ball valves are tted to ensure ease of maintenance during shut down periods.
Discharge Line Ball Valves
Discharge line ball valves are tted to ensure ease of maintenance during shut down periods.
Filter Driers
Filter driers are tted to ensure that the expansion device is protected from any potential contaminants in the system.
This can be serviced with changeable inner cores.
HP / LP Transducers and Switches
HP / LP Transducers and switches are tted to the unit to protect against high or low pressures.
High pressure switches are manual reset.
