Characteristics
The compressor
The unit is equiped with semi-hermetic screw compressor, compared with the piston compressor, semi-hermetic screw compressor has two advantages:
• Less parts(About 1/3 of the piston compressor), simple structure, less wearing parts, high reliability and long life.
• Compressor suction and exhaust uniform, exhaust temperature is low, vibration is small, not sensitive to wet compression, anti-liquid strike ability.
Tube-fin air-cooled condenser
The tube-fin air-cooled condenser adopts the inverted "V" type layout, on the one hand, it improves the space utilization ratio, increases the heat exchange area, on the other hand, it improves the airflow and heat transfer efficiency, so that improve the unit's cooling and heating capacity.
Throttling equipment
For expansion valve, we select the most advanced products, with a compact overall design, rugged stainless steel diaphragm, and in a wide range of operating conditions to provide stable and accurate control.
Tube-shell evaporator
Using shell and tube structure, the outside is proceeded with fire-retardant,waterproof insulation materials, water side of the working pressure is 1.0MPa.
Evaporator with PVC plastic water board, corrosion resistance. Chilled water along the diaphragm up and down circuitous flow, in order to increase the spoiler effect to improve the evaporator heat transfer capacity.
Using the latest DAC corrugated spiral high efficiency heat transfer tubes, strengthen the fluorine side heat transfer capacity, improve the heat transfer coefficient to ensure that the unit good refrigeration and heating performance.
Electronic control
Air-cooled hot and cold water unit uses a microcomputer as the core of the control system, the control system control precision, anti-interference ability to ensure that the unit safe, reliable and economical operation.
Energy regulation automatic control can make the unit always in the best economic mode point efficient operation.
Protection function complete unit with overload, short circuit protection, frost protection, high and low voltage protection, overheating protection and other functions.
Technical Data
*Â The performance values refer to the following conditions:
Cooling: ambient air temperature 35ºC; evaporator water in/out temperature 12/7ºC.
Heating: ambient air temperature DB 7ºC, WB 6ºC; condenser water in/out temperature 40/45ºC.
**Â Sound pressure measured at a distance of 1 m and a height of 1.5 m above the ground in a clear field.

Light range of conveyors is developed to convey grains, seeds, pigments, additives and meal type of products where material is free flowing and less abrasive environment. Bush chain with bolted UHMWPE paddle is used to convey materials, which run on bottom plate and return brackets. UHMWPE bottom and top liners are available on request. Due to its design and product nature, these conveyors can operate at high chain speed.
Conveyor casings and bolt holes are cut using CNS laser machines and folded. These conveyors are specifically designed to reduce fabrication and assembly duration, which makes them very economical.
Chain conveyors can be designed in a horizontal, inclined, or in vertical arrangement. Conveyor`s bottom and side panels are made off 3mm folded galvanized sheets with 2mm top cover. Drive and tail units fitted with flanged bearing housings with lip seals, Plummer block bearing housing are also available on request.
Hardened head end and tail sprockets are mounted with keys.
Conveyor roller chains and standard sprockets are widely used for these applications.
Tail end comes with adjustable screw take up in standard design; self-cleaning tail end with screw adjustment on driven is available for food products.
