hotspring® coil heaters(type WRP)

With this brochure ZRE presents a wide product

spectrum of coil heaters:l Starting with hotspring®/Micro up to

hotspring®/Maxi with different lengths and

diameters.l E. g. hotspring® coil heaters casted in brassor with clamping mechanism and screwing as

heating elements for different applications.l Heating systems such as the heated nozzle

hotcone® (type BMD).l Special product such as hotslot®.

Already in 1980 hotset had been one idea ahead

when they presented the first round hotspring®

coil heater (type WRP Ø 3.3). Since then further

innovations have been made: hotspring®/Mini, flat

and square coil heater (hotspring®/F resp. hot-

spring®/Q), hotspring®/Maxi as well as hot-

spring®/Micro.

Special product variants are consequently develo-

ped according to the requirements of the user.

The heated machine nozzle hotcone® (type BMD)

is of high potential for the plastic processing

industry.

This product is compact, sealed systems based on

the heating with a hotspring®/Maxi with corres-

ponding power distribution.

Hotspring® coil heaters inserted in hotslot® ensu-

re a precise heating with any power distribution

possible. This innovation as well as the humidity

resistant coil heaters according to IP 65 (hot-

spring® Ø 3.3, hotspring®/F 2.2 x 4.2, hot-

spring®/F 1.8 x 3.2, hotspring®/Q 3.0 x 3.0, hot-

spring® Ø 4.0) emphasize the consistant align-

ment to new challenges.

Profit from our long time experience to fit your

needs.

Installation and storage instructionInstallation

l please secure that heating elements will only

be connectedfrom instructed operators.l bear in mind the minimum bending radius,

formed parts cannot be changed into

another shape.l length of the connection head plus 5 mm of

the unheated zone are not bendable.l do not hold onto the connection head.l only use non-electrically conductive sprays

and pastes for installation (e.g. hotspring®/K

or hotspring®/M) (Our “Isolite-Spray” is

especially designed for these applications).l heating elements and sensors should be

installed immovable; Attention: Depending

on hotspring ®-type an uplifting from the

tool during heating is possible!

Temperature Controllersl temperature controllers have to match

the power consumption and the used

temperature sensor (suitable

temperature controllers are available

from hotset)l only install temperature controllers with

automatic soft start function so that any

moisture which may have entered the

heating element will escape slowly

Connessionel protect connections against the ingress of liquids (e.g. oil,plastic material) and gases to avoid

short circuitsl install the connections away from sharp edges or parts as this may also cause short circuits

(appropriate accessories to protect connection leads are available from hotset)l protect connection leads against the effects of temperature or lay them accordinglyl please take the maximum temperature depending on connection art from the catalogue datal tool temperature must stay below corrosion point for heaters with current return to heater sheath

to guarantee smooth current transfer (welded or soldered on connections available for

applications with temperatures over corrosion point)l pay attention to the connection voltagel thermocouple leads: pay attention to the correct polarization and complete protection against

accidental contact of heating elements with an integrated thermocouplel between power conductors and thermocouple is only a basic insulationl thermo leads and contacts must be shock protected

Operation

Storagel store at room temperature in

a dry place

General informationl for further security information for special applica-

tions please take a look at our order confirmation.l if our heating elements are delivered with connection

leads without insulation (naked connection) or with

removable insulation (covered with GLS-sleeving),

the customer himself has totake care about the

protection against electricity.

l make sure that the heating element

is definitely groundedl security procedures for the handling

of electrical items and applications

must be followedl do not touch heating elements while in

use because they can get very hotl please secure that heating elements

can not touch flammable material

while in usel do not heat hotslot® unmountedl hotslot® are easily damagable by

pressure or other affects
