FRAME
Self supporting frame made of extruded aluminium profiles, connected with 3 way joints - no use is made of any screws that protrude from the framework. The frame sits on a base of galvanised steel spars. The frame is fitted with polyurethane injected sandwich panels - the outer steel surface has been pre-painted RAL 9002. The seal is guaranteed by specific long-duration gaskets ensuring that the panels remain perfectly airtight in time despite the pressure that is created during normal operation.
Condensing Section
COMPRESSORS
Hermetic scroll compressors equipped with crankase heater and klixon for overload protection and complete with oil sight glass. The compressors are mounted on rubber shock absorbers.
CONDENSER (EVAPORATOR in the H version)
Copper tube and aluminium finned equipped with a protection grill.
AXIAL FANS
With aerodynamic designed blades manufactured, directly coupled to a three phase electric motor with external rotor and fitted with thermal contact. A safety fan guard is fitted on air flow discharge.
REFRIGERANT CIRCUIT
The refrigerant circuit includes: dryer, sightglass, thermostatic electronic valve “schrader” valve, and solenoid valve. To protect the refrigerant circuit, following devices are fitted: manual reset high pressure switch, automatic reset low pressure switch. Furthermore, where required, manual reset safety pressure switch and safety valve are also fitted. In the heat pump unit version (H) the refrigerant circuit also has the following fitted: double termostatic electronic valve, 4-way valve, non-return valve, solenoid valve, liquid receiver.
ELECTRICAL BOARD
Weather proof to IP54 protection level. The board is fitted with: main interlocking automatic circuit breaker, main fuses, compressor contactor, auxiliary circuit transformer, air handling section control. The board also has a microprocessor to automatically control the unit, complete with a display of the operating status as well as all alarm situations.
Thanks to efficient production models our roof-top air-conditioning equipment fully conforms to Italian and international standards. Together with quality management standards ACM Kälte Klima develops own product portfolio offering essential selection of standard roof top equipment and tailor made solutions in line with client’s requirements. Scroll compressors for heating and cooling of industrial and commercial buildings are made using high quality materials and brilliant ideas of our engineering team.
Roof positioning of these air-conditioning machines is possible thanks to a particular construction calculated to be set on the top floor of the industrial buildings. Installation space helps to overtake some limits of the cabinet systems: roof-top air-conditioning are more powerful thanks to its size, and more silent thanks to its external placement.
- ACM Kälte Klima products are planned to obtain an excellent environmental comfort with minimum energy consumption: latest advanced technologies ensure stable cost-effective solution for bigger spaces.
- One of the substantial advantages of roof-based ACM Kälte Klima air-conditioners is its low environmental impact: in addition to considerable energy savings, our housetop solutions use the green R410A refrigerant that doesn’t damage the ozone layer, as it is free from chlorine atoms.
- High quality materials and attention to details make our roof-top air-conditioning solutions reliable and durable in any operating conditions.
