Features

Compact

■ Light-weighted, good-looking appearance, and compact and solid structure.

■ 235 mm height, allowing installation on the ceiling with a limited space.

Low-noise

■ Low-noise motor for driving the low speed fan with a wide impeller; strictly tested before delivery.

■ Precise distance between the impeller inlet/outlet and the heat exchanger for more reasonable air ow

distribution.

■ Highly efcient sound-absorbing and heat-preserving materials inside to minimize noises produced by the unit.

Reliable

■ Single-phase capacitor motor with the protection grade IP20 and insulation grade B to ensure operation safety.

■ Permanently lubricated and sealed ball bearing with high precision, which is provided by internationally famous

brands and receives processing including hardening and tempering as well as chroming.

■ Motor power outlet wires protected by metal hoses to ensure its durability.

■ Working pressure up to 1.6 MPa and test pressure up to 2.0 MPa for the heat exchanger to endure high

pressures and prevent leakage.

High Efciency

■ Heat exchanger with the high-quality mechanically expanded copper pipe and hydrophilic aluminum ns to

ensure high efciency.

■ Intensied air supply using a large air ow fan with a wide impeller to maximize the heat transfer performance.

■ Precise matching of the fan and motor to guarantee the maximum cooling capacity but a low power input.

Flexible

■ Multiple external static pressures designed based on the unit’s cooling capacity, meeting the air supply

requirements at different distances.

■ Optional bottom return air plenum or back return air plenum with support for onsite changes, featuring time

saving.

■ Variable accessories for more options.

Anti-leakage

■ Delicate condensate-proof drain pan made of the cold-rolled steel through one-time impact molding, with

coating on both sides and high-quality heat-preserving materials on the exterior.

■ Unique independent mounting bracket without soldering seams or joints, requiring no bolts for xing to prevent

damages to the drain pan heat-preserving layer or cold bridges.

■ Tilt structure for rapid condensate water drainage.
