Import Chiller Controller — Buy in Bulk from Supplier in South Korea (Republic Of Korea)

Dotech Inc. manufactures a chiller controller designed for modern refrigeration plants. The device employs a Super PID control algorithm that delivers precise temperature regulation and reduces energy consumption. Dual sensor inputs feed real‑time data to the controller, enabling accurate set‑point management for both reciprocating and scroll compressors. The unit features a graphic user interface that simplifies configuration and monitoring for technicians.

In the control‑systems market, controllers typically operate from 220 V to 240 V AC and communicate via Modbus RTU, providing seamless integration with building management systems. Temperature accuracy of +/-0.5°C is common for this class of equipment, and a typical power draw is around 150 W. The controller’s enclosure meets IP‑54 protection, guarding against dust and splashing water in industrial environments. These standard specifications align with IEC 61508 functional safety requirements for refrigeration control devices.

Primary users include food‑processing plants, pharmaceutical manufacturers and large‑scale HVAC contractors who need reliable temperature control. Buyers should request the full wiring diagram, firmware version and confirmation of the controller’s compatibility with their existing compressor fleet. Trade discussions should cover MOQ, payment method, warranty period and the preferred Incoterm before finalising the purchase with Dotech Inc.
