Функции

CASING/STRUCTURE

The casing is made of zinc coated galvanised steel sheets. It is further treated with an electrostatic powder coat then over baked to provide a weather resistant finish to suit the harsh climate.

COMPRESSOR

H ighly e fficient and reliable DC Inverter scroll c ompressors.

CONDENSER AND EVAPORATOR

The condenser and evaporator coils are manufactured from seamless copper tubes mechanically bonded to b lue hydrophilic aluminium fins to ensure optimum heat transfer . The shoulder of each fin adjoins the shoulder of the adjacent fin, completely encasing the copper tubes for maximum heat transfer. The generously sized coils provide ample capacity under all normal operating conditions. All coils are pressure tested at the factory to avoid leakage. To improve corrosion resistance, a hydrophilic Gold Fin is provided as optional.

CONDENSER FAN AND MOTOR

Direct driven propeller axial fans are used for maximum condensing efficiency.

EVAPORATOR FAN AND MOTOR

EC is fitted with a plug-fan ensuring that no belt particles can be carried away into the building , t his ventilation system is compliant with EN13779 air quality norm. EC plug fans deliver exact airflow requirements while minimising power usage, and are up to 50% more efficient versus traditional belt and pulley systems.

INSULATION

Ripple type acoustic insulation for compressor section , low noise. To prevent the likelihood of condensation occurring the unit is equipped with 10mm Polyethylene panel insulation for coil & fan section .

S AFETY

Electric panel consists of breakers and contactors for compressors and fan motors, phase sequence relay and other necessary protection devices for the main components. All electric parts are Schneider Electric brand.

EASY INSTALLATION AND MAINTENANCE

The base beams are fixed and provide a rigid foundation for the entire unit. The bea m has forklift slots or rigging holes for easy handling. To keep installation as hassle-free as possible, Sendo units are fully factory assembled , tested and charged with R410A refrigerant. Only ductwork and external wiring connections are required to make the units completely operable ensuring rapid, low-cost installation. For ease of commissioning and maintenance, Sendo units include easy access to the electrical cabinet and major refrigeration components. The unit provides external pressure gauge for convenient and fast checking system pressure without removing the panel. If the unit is in running with abnormal operation, the controller will show the error code for easy troubleshooting.
