Copper Tube Evaporator Coil for Environmental Chamber

Environmental chambers demand stable, precise temperature & humidity control for product reliability testing across electronics, automotive components, battery and material‑testing industries. The evaporator coil is the core heat‑transfer component that directly determines chamber temperature uniformity, cooling speed and anti‑condensation performance.

Our custom‑built copper tube evaporator coils are purpose‑engineered for environmental chamber systems. Adopting high‑conductivity seamless copper tubes paired with high‑quality aluminium fins (hydrophilic coating optional), these coils deliver efficient heat exchange under frequent cycling cooling‑heating operating conditions.

Key Product Features

Material selection: High‑purity seamless copper tubes, compatible with R404A, R23, R134a and other refrigerants. Hydrophilic fin treatment minimizes water bridging and guarantees stable humidity control.

Custom dimensional service: 1:1 duplication from customer samples or engineering drawings. We adjust tube diameter, fin spacing, coil rows and circuit layout to match chamber cooling capacity requirements.

Rigorous pressure‑leak test: Every coil undergoes strict helium leak testing to avoid refrigerant leakage during long‑term cyclic temperature shock operation.

Anti‑frost & de‑icing friendly fin design: Optimized fin pitch for low‑temperature working conditions, reducing frost accumulation and supporting regular defrost cycles.

Flexible connection options: Suction & liquid return ports can be configured on left‑hand or right‑hand side to fit different environmental chamber cabinet layouts.
