商品紹介

The reheat coil is positioned downstream of a cooling coil so it can add sensible heat without increasing air moisture. Its shallow copper-tube and aluminum-fin construction minimizes air pressure drop while providing enough surface area for precise leaving-temperature control. Low water volume and short circuits respond quickly to a modulating valve, making the coil suitable for tight cleanroom temperature and humidity sequences.

主要な特徴

One- or two-row construction limits fan energy while delivering controlled sensible reheat.

Small internal water volume responds rapidly when the modulating valve changes position.

Accessible vents and drains prevent air binding during low-flow operation.

Compact casing fits between cooling-coil, fan and final-filter sections in constrained AHUs.

お客様の製品に関する懸念事項

Reheat must correct overcooled supply air precisely without adding excessive pressure drop or fighting the cooling sequence.

Air leaves the dehumidifying coil too cold for the occupied zone.A downstream hydronic coil adds only sensible heat and preserves the achieved moisture content.

An oversized multi-row coil causes sluggish temperature control.A shallow low-volume circuit responds quickly to modulating water flow.

Excessive fin resistance increases cleanroom fan power.A one- or two-row face and appropriate fin pitch minimize air-side pressure drop.

Simultaneous cooling and reheat waste plant energy.Heat-recovery or low-temperature return water can supply the reheat duty when available.
