Rooftop packaged unit
LARK Rooftop Packaged Units are single packaged units which are factory assembled, tested and shipped completely with compressor, evaporator and condenser coils, fans and controls. These packages are designed for outdoor installation, and they may be used for cooling only or cooling and heat pump.
The units are ideal for residential, commercial and industrial applications and are available in nominal cooling capacity from 9.9 kW to 188.5 kW. Quality design and construction make LARK air-cooled rooftop package units with hermetic scroll compressors the preferred applications and easy installation and maintenance. Operation range of outdoor temperature is from -10°C to 45°C.
FEATURES
Efficient. These reverse cycle (heat pump) air conditioners provide one of the most efficient forms of heating you can invest in. For every 1 kW of power consumed, up to 2.8 kW of heat is generated. For every 1 kW of power consumed, up to 3.1 kW of heat is generated. Each outdoor unit incorporates high efficiency scroll compressors. Heat exchange coils use high efficient tube for better heat transfer.
Performance. These systems have been designed and tested to perform in ambient conditions as low as -10°C and as high as 45°C. For the models from LAAHP 25 to LAAHP 190 belt drive fan motors are used to match the supply air requirements. The smaller units( models from LAAHP 10 to LAAHP 20 ) have 3 speed direct drive fans for adjusting air flows.
Durable. Our packaged systems are built tough to withstand all weathers. Their durable construction ensures a long life and excellent return on your investment. The outdoor air coils' aluminum fins are epoxy coated for extra protection in corrosive environments, e.g. salt laden sea air. Cabinets are constructed from high grade steel - polyester powder coated for all weather protection. External fasteners are stainless steel or galvanized type. Corrosion resistant drain trays are also included.
Insulation. Indoor air sections are generously insulated to reduce condensation and contain noise.
More Safe. The refrigeration system includes a number of protection facilities, including: HP and LP switches, phase sequence relay, circuit breaker control etc.
Economy. Some models feature the flexibility and economy of 2~4 stages operation. Compressors are progressively switched on only as they are needed. This has the added advantage of lowering start-up current.
Economizer Option. If the outdoor air heat content or temperature is below that of the return air, a fresh air damper opens and the return air damper closes to provide the first stage of cooling. Operating costs are reduced as the compressor(s) will only operate to provide more cooling if it is required.
Fresh Air Introduction. An optional fresh air damper is available for most models. For applications using high proportions of fresh air (50%+) a hot gas bypass and HP fan speed controller are recommended and are available as options.
Peace of mind. The manufacturer operates a quality management system that conforms to international standard like CE, ISO14001, ISO9001:2000. LARK products have been chosen, against worldwide competition, for use in some of the most exclusive projects — chosen because of their proven efficiency, durability, performance, reliability and value.
Easy service. Quick release fasteners are provided on electrical and compressor panel.
Quiet design. Apartments are provided on electrical and compressor section, low noise.
