TECHNICAL DESCRIPTION:

The heater is designed to directly heat any liquid in domestic and industrial installations, e.g. in boilers, hot

water tanks, water preheaters or flow heaters. The heater's head must be fully submerged in the liquid at all

times during operation. Suitable for applications where it is necessary to immediately control the

temperature of the liquid. Tubular heaters have good thermal, electrical and mechanical properties. The

heater consists of two parts - the heating part and the terminal plate. The heating section consists of three

heating elements made of brass, steel or stainless steel (D8.5 mm; copper, stainless steel 17 248 / INCOLOY

800) with heavily compacted insulation material in which the heating coil is sealed. All the materials used

ensure maximum corrosion protection. The U-shaped heating elements are attached to the head with an

M48x2 or G6/4" thread, made of stainless steel or brass. The terminal plate is made of cast aluminium with

IP54 (TRG11 and 31) or plastic with IP67 (TRG13). It includes a control single-phase or three-phase capillary

thermostat, a digital thermostat and a thermal fuse to prevent the heater from overheating, a neon lamp

indicating the status (heating / not heating) and a control knob or digital thermostat keypad. A wide range of

temperature ranges, material designs or surface finishes can be supplied upon request. The heaters are easily

installed using a socket with an M48x2 or G6/4" thread. An optional accessory, is the possibility to choose a

nut of the pertinent thread, where the heater is not installed in the lug, but only in the 48-50mm hole (for

M48x2 or G6/4" thread). Electrical supply is possible from both sides via an OBO-VTEC grommet. The

electrical leads are connected directly to the thermostat terminals and not to the heating rods. The heater

must be earthed in line with the relevant standards. The requisite temperature is set by the control knob or

via the digital thermostat display, accessible from the front side of the Al terminal plate (TRG11 and TRG31),

the neon lamp inside the ABS terminal plate (TRG13) shows whether it is heating or not. The TRG11 series

heater comes with or without a power cable. The TRG13 and TRG31 heaters always come with the

corresponding wiring.

TRG series heaters can be equipped with thermostats with the following parameters:
