NOXT temperature and humidity controllers regulate cabinet climate by controlling heaters, cooling fans, and dehumidifiers to help prevent condensation, overheating, and moisture damage.
Our range includes mechanical thermostats, electronic hygrostats, and digital controllers for electrical enclosures, switchgear, energy storage systems, and industrial control panels.
A cabinet heater and a fan only earn their place when they switch at the right moment. NOXT builds the controllers that decide that moment. The mechanical KTS and KTO series need no power wiring and switch on a 7K differential, so fans and heaters settle into a steady cycle instead of clicking every minute. The electronic SK3118 measures humidity to ±3%RH and sets its threshold anywhere from 35% to 95%.
For a logged or displayed reading, the CZCS-F digital unit holds temperature to ±0.1°C on an LCD. All three families fit the same DIN-rail and cabinet climate system, so a buyer orders the controller, heater, dehumidifier and fan together in one package.

Use the mechanical series. KTS and KTO are cheaper and need no power wiring, switching on the 7K differential.
Go electronic. SK3118 for adjustable thresholds from 35% to 95%RH, MFR012 for sites with electrical interference.
Use the CZCS-F digital unit. It holds temperature to u00b10.1u00b0C and shows the reading on an LCD.
Pair NC contacts with heaters and NO contacts with fans, so the load fails safe if the controller loses power.
Compliance tested and documented per batch
Covered on every controller and hygrostat
Fits standard cabinet DIN rails
Custom colors, logo and calibration
The mechanical series (KTS, KTO, MFR) needs none. The SK3118 accepts DC24V-230V, and the CZCS-F runs on AC220V with a DC12V option.
Normally open (KTS011) closes when temperature rises to start a cooling fan. Normally closed (KTO011) opens on high temperature and keeps the heater running below the threshold. Use both for heating plus cooling.
Yes. The CZCS-F supports field calibration of both sensors from the front panel, and the SK3118 threshold is adjustable from 35% to 95%RH.
7K (u00b14K) on the mechanical thermostats, which prevents rapid on-off cycling. The electronic series uses roughly 4%RH.
