Exentec offers precise Climate Control Systems for sensitive cleanroom processes. Stable conditions are the foundation of high-performance production. Our control system products ensure precisely controlled temperature and air quality with energy-efficiency and reliability at their core. In semiconductor and high-tech production, temperature and air purity define product quality and yield. Even the smallest fluctuation can cause costly quality issues. The right climate ensures quality and reduces the rejection rate in production. Decisive parameters are the highly precise stabilization of temperature and humidity as well as the assurance of air cleanliness in regards to particles and chemical contamination.
Exploring Exentec's MoKli Climate Control System
MoKli is a compact recirculating air-conditioning system for precise temperature and air-quality control in cleanrooms. An optional catalytically activated chemical filter (AMC Filter) removes airborne molecular contaminants including acids, bases, organic compounds, and hydrogen peroxide (H₂O₂) with >98% efficiency. A fresh-air ratio from 5% up to 10% ensures controlled environments at minimal energy demand.
MoKli has a service-friendly modular construction. Its heat exchanger, heater, and filter modules are fully extractable for easy access and maintenance. This minimizes downtime and service costs.

Key figures:
- Air volume up to 3.000 m³/h
- Temperature stability ±0,1 K to ± 5mK (depending on configuration)

KS2
The precision air‑conditioning unit KS2 can heat, cool, humidify, and dehumidify process air. For temperature control, it contains a water‑cooled, hermetically sealed refrigeration cycle and an electric heating coil. For humidity control, direct evaporators and steam humidifiers are used. The specifications of the process air can be optimized for specific setpoints.
