ALRE Capillary Thermostats RTKSA

An exciting new range of capillary thermostats replacing the former JET-40 - JET 41F and KR, LR and WR ranges of boiler thermostats.

RTKSA Plant Room Thermostat


RTKSA plant room thermostats were specially developed for use in industrial halls, exhibition halls, air halls and greenhouses. When used as a frost protection controller, the higher tolerances at the end of the scale must be observed.

RTKSA-100.010 -10 to + 40 deg C, TR external setting
RTKSA-101.010 -10 to + 40 deg C, TR internal setting
RTKSA-100.110 0 to + 50 deg C, TR external setting
RTKSA-101.110 0 to + 50 deg C, TR internal setting

Compared to the old models:

JET-40 0 to +35 deg C RTKSA-100.010 -10 to +40 deg C
JET-40F 0 to +35 deg C RTKSA-101.010 -10 to +40 deg C
JET-41 0 to +70 deg C RTKSA-100.110 0 to +50 deg C
JET-41F 0 to +70 deg C RTKSA-101.110 0 to +50 deg C

RTKSA Plant Room Double Thermostat

RTKSA plant room thermostats were specially developed for use in industrial halls, exhibition halls, air halls and greenhouses. When used as a frost protection controller, the higher tolerances at the end of the scale must be observed.

2 separate setting ranges, heating and/or cooling.

RTKSA-114.110 0 to +50 deg C, 2 x internal setting
RTKSA-114.010 -10 to +40 deg C, 2 x internal setting

The RTKSA-114.110 replaces the JET-30 and JET-31 models.

RTKSA Universal Capillary Thermostat


A brand new series of capillary thermostats replacing the former KR, LR and WR ranges. Special features include extendable capillary, a transparent front cover for easy viewing, and wider temperature ranges reducing the numbers of individual models and creating a much more versatile thermostat.

Developed for us in heating technology in boiler systems or storage tanks, district heating transfer stations and heat transfer systems. In ventilation technology they are designed to monitor supply air or as limiters for electrical heating coils as well as for controlling and monitoring temperatures in pipelines and tanks.

Immersion sleeves, protection coils and mounting sets are available but not included with the basic model. The JZ-29 mounting set must be used in conjunction with immersion sleeves or protection coils. When used as contact controller (pipe mounting), mounting set JZ-31 must be used.
