STjh eight-row direct-expansion cooling coil with a deep casing and expanded refrigerant circuit array on white.

STJH-DIRECT-EXPANSION-COOLING-COIL-8ROW

Direct-Expansion Cooling Coil Eight-Row

The deepest DX evaporator in the group for high latent loads and low leaving-air temperatures.

Eight-row maximum depth
13.5 in published casing
High-latent counterflow design

Giới thiệu Sản phẩm

This eight-row evaporator extends the casing to 13.5 in and carries the greatest selected refrigerant circuit and surface area. Approximately 500 fpm is a common face-velocity basis, subject to wet-coil carryover and performance rating. It is intended for high-outdoor-air and precision-conditioning systems where deeper cooling justifies the greater air pressure drop, condensate production and refrigerant distribution complexity.

Các tính năng chính

Maximum latent capability

The deep cold surface promotes lower leaving temperature and greater moisture removal.

Expanded refrigerant circuiting

Additional parallel circuits distribute capacity across a large evaporator face.

Precision make-up-air duty

The core supports demanding cleanroom supply conditions that shallow DX coils cannot reach.

Applications

For high-latent cleanroom make-up air, low-temperature DX supply systems and precision manufacturing ventilation.

Solutions for Your Application

Oil return becomes unreliable through numerous low-load refrigerant circuits.Size circuit velocity and staging for part-load operation and coordinate distributor and suction-header geometry.

The deep wet core produces unacceptable fan loss and water carryover.Rate the complete coil wet, enlarge face area and add an eliminator where the selected velocity requires it.

Các tùy chọn có sẵn

Confirm refrigerant, load profile, suction conditions, circuits, distributors, face size, fin spacing, coating, casing and drainage.
