One idea ahead

hotspring Coil Heaters

hotset was al­ready in 1980 one idea ahead as they pre­sent­ed the first round hot­spring coil heater. Since then fur­ther in­no­va­tions have been made: hotspring®/Mini (type WRP 1,3 x 2,3), flat and square, hotspring®/Maxi (type WRP 4,8 x 8,6) as well as hotspring®/Micro (type WRP 1,3 x 2,3).

This in­no­va­tion as well as the hu­mid­i­ty-re­sis­tant coil heaters ac­cord­ing to I.P. 65 (type WRP/F 2.2 x 4.2 — WRP/Q 3.0 x 3.0) em­pha­size the con­se­quente align­ment to new challenges.

Application examples

hotset of­fers a wide prod­uct range of hot­spring coiled tub­ing car­tridges: Start­ing from the hot­spring Mi­cro (type WRP/F 1.0 x 1.6) to the hot­spring Maxi (type WRP 4.8 x 8.6) in a wide va­ri­ety of lengths and di­am­e­ters, hot­spring with sleeve and clamp­ing mech­a­nism as heat­ing el­e­ments for a wide va­ri­ety of ap­pli­ca­tions as well as a wide range of applications.

hotspring with reflection tube

When us­ing hot­spring coil heaters with a re­flec­tion tube the max­i­mum sur­face load in­creas­es. Fur­ther­more the re­flec­tion tube pro­tects the heater from me­chan­i­cal dam­ages. The re­flec­tion tube can be de­liv­ered for a lot of hot­spring di­men­sions. Ad­di­tion­al­ly it is pos­si­ble to car­ry out a con­trolled tem­per­a­ture mea­sure­ment with a coiled-in or in­te­grat­ed thermocouple.

hotslot Nozzle Heating Elements

The hot­slot is a heat­ing el­e­ment for heat­ing hot run­ner noz­zles for plas­tic in­jec­tion mold­ing. It is based on the proven tech­nol­o­gy of the “hot­spring Mi­ni” and “hot­spring Mi­cro” coiled tub­ing car­tridges, which are pressed in­to a brass car­ri­er tube.

Due to its low wall thick­ness, start­ing at 1.5 mm for the hot­slot Mi­cro, the hot­slot al­lows min­i­mum nest dis­tances. In ad­di­tion to the con­nec­tion de­signs, anal­o­gous to the hot­spring coiled tub­ing car­tridge, the course of the groove for the heater to be pressed in can al­so be in­di­vid­u­al­ly se­lect­ed for the hot­slot. The pow­er dis­tri­b­u­tion is thus ab­solute­ly pre­cise and re­pro­ducible to en­sure tar­get­ed and ho­mo­ge­neous tem­per­a­ture con­trol in the man­u­fac­tur­ing process. 

The com­bi­na­tion of brass car­ri­er and he­li­cal car­tridge al­lows for low-pow­er zones that would be in­con­ceiv­able with a sim­ple he­li­cal car­tridge. Even me­an­der wind­ings, re­cess­es, aper­tures and bores as well as de­signs as a flat plate heat­ing el­e­ment are pos­si­ble. To fa­cil­i­tate sub­se­quent dis­as­sem­bly, the car­ri­er tube can be nickel-plated.

Ther­mo­cou­ples are in­te­grat­ed with an ad­di­tion­al slot and can al­so be placed in­di­vid­u­al­ly. On re­quest, hotset pro­duces the hot­slot with a slot­ted or par­tial­ly slot­ted car­ri­er tube with me­an­der wind­ing. This of­fers the ad­van­tage that the ther­mo­cou­ple can be changed eas­i­ly if re­quired. In ad­di­tion to the cus­tomized op­tions, hotset al­so of­fers sev­er­al vari­ants of the hot­slot with ther­mo­cou­ple as stan­dard items from stock.
