Cooling capacity:15KW-390KWutilization area: dozens of square meters to hundreds of thousands of
square meters
Direct Expansion air cooled unit can exchange heat directly between
refrigerant and air to be processed.Feature:1. Case body patent designs
(1). The case body uses high-strength aluminum material
(2). Ultra-low air leakage ratio
(3). Completely cut-off cold bridge,good heat preservation effect2. Polyurethane sealed case body with patent design provides excellent
sound insulation effect.3.Remote Intelligent Control System
Cold-proof air: It has cold-proof air on startup, cold-proof air on shutdown
and minimum temperature setting restrictions.
Remote Control: Users and manufacturers both can control the unit remotely
through computer or mobile APP.
4.The unit usesinternal screw tube and hydrophilic slotted fin, andthe heat
transfer efficiency increases by 20%.
5.Double Electronic Expansion Valve in Main and Auxiliary Circuitsto throttle.
Precise temperature control, more energy-saving operation.6.Complete protection function:flow rate protection, LP HP protection, anti-freezing
protection, fan overload protection, compressor overload, overheat protection,
phase order protection etc.
Control lock function: can lock the operation of the unit, only the switch is effective to
prevent misoperation.7. Excellent noise control.Big fan blade and low-speed fan ensures low running noise.8.Easy toinstall andmaintain
only the duct design,no need accessories such as pumps.
No special machine room
High operability of the process
Short construction period9.Widely application
Wide range of temperature control
High cleanliness control
Compact unit structure
