Two platforms sized to your mould: EHRTC-PM1 and EHRTC-RM2
Both series offer PID Auto-Tune, Stand-By, thermocouple fault protection and 537 °C operation. The difference is the power stage: external and easily accessible on the PM1, built into every fan-cooled module on the RM2.
EHRTC-PM1 Hot Runner Temperature Controller
Semi-modular rack system with external power stage. 1–12 zones, 100% made in Türkiye.

EHRTC-RM2 Hot Runner Temperature Controller
Modular rack system with built-in power stage and fan cooling per zone. 4–12 zones.

Frequently asked questions
The questions we hear most about hot runner control, zone counts, service and warranty.
All FAQsWhat is a hot runner temperature controller?
A hot runner controller measures the temperature of the runner heaters in a plastic injection mould via thermocouple feedback and keeps it constant with a PID algorithm. Each zone is controlled independently, so the melt temperature stays even across all nozzles, scrap drops and part quality improves.
How many zones do Elotek controllers support?
EHRTC-PM1 is built in 1, 2, 4, 6, 8, 10 and 12 zones; EHRTC-RM2 in 4, 6, 8, 10 and 12 zones as standard. Higher zone counts are configured on request.
Are the controllers made in Türkiye?
Yes. All EHRTC hot runner controllers, SSRs and DC motor control boards are 100% designed and manufactured at our facility in İkitelli OSB, Istanbul.
How long does technical service take?
For Elotek-made units, service takes at most 3 business days including parts supply. After repair approval, the unit is repaired and shipped within 4 business days.
What is the warranty period?
All products sold via elotek.com.tr carry at least a two-year manufacturer or authorised distributor warranty.
