Frame structure

The latest reinforced aluminum alloy profile is used, with surface being subject to anodic oxidation treatment and internal foamed, to prevent the sweat phenomenon on the frame surface, being firm and beautiful.

Panel structure

Double-skin panel structure, with 25mm thickness foam insulation, galvanized steel sheet. With beautiful appearance, anti-corrosion, The panel has firm structure and excellent performance against sound and vibration.

Structure of heat exchange oil

The heat exchange tubes are arranged in the triangular staggered manner, generally 4-8 rows; the heat exchanges tubes are made of high-quality copper (TP2).

The high-efficient heat exchanger is made on U.S. OAK assembly line. After overall passing through, the copper tube is closely integrated with the aluminum pieces, providing excellent heat transfer effect, satisfactory for the occasions of the thermal performance requirements; precision processing machinery and strict processing control ensure uniform piece distance and tight tube expansion.

The external frame of the coil is bent formed with galvanized steel sheet, being firm and durable; bolt connections are used to prevent rust due to welding of the galvanized layer.

The design work pressure of the coil is 16 bars, test pressure 25bars.

Fans and motors

Double air-intake centrifugal efficient fans , with international famous brands fan bearing, easy for repair and maintenance.

Famous fan motors are used, with insulation class B so as to ensure the quality and service life; In addition, the motors of given brands can be provided when user requires so that motor insulation class can be enhanced in order to meet the needs of different occasions.

The fans are belt-driven , i.e. high-quality V-shaped belts; belt pulleys are precisely machined to ensure concentricity and in accurate matching of the belt; after fans and motors assembly, the second running dynamic balance inspection is carried out in order to achieve the minimum vibration and the highest transmission efficiency.

The bases of fans and motors are all equipped with suitable damper spring shock absorbers; fan outlets and outside box are all flexibly connected using anti-corrosive and moisture-resistant canvas.

Coil design

According to varied flows, temperature differences and operating conditions, different internal process designs are adopted in order to maintain coil heat exchange performance and coil water pressure drop at a reasonable and efficient levels and reduce application difficulty; designed head-on wind speed is 2.5m/s-2.8m/s, and special design requirements are also acceptable.

Filters

Double nylon embossed nets are used, easy for replacement and removal, can be cleaned and used repeatedly. Non-woven plate filter can also be fitted at the air intake when required, or a new fresh return air mixing box be used.

Large dust capacity: under the designed final resistance (double the initial resistance), the dust capacity per square meter is more than 100g.
