Product Overview

Electrical and automation cabinets often contain heat-generating components such as PLCs, VFDs, power supplies, relays, industrial switches, meters and communication devices. If heat is not removed properly, internal cabinet temperature can rise and reduce component life or cause equipment faults.

The HPC1000T helps solve cabinet heating problems by delivering dedicated enclosure cooling with short internal air paths and uniform cooling air distribution. It is suitable for medium-sized cabinets and panels where stable temperature control is required.

Package Details

Installation and Mounting

The HPC1000T is designed for door-mounted or face-mounted installation on an electrical cabinet. The product drawing indicates a flange size of 484 × 784mm and a 24 × Ø6 mounting-hole arrangement for the larger HPC1000T / HPC1500T body size.

Why Use Closed-Loop Cabinet Cooling?

Open ventilation fans can introduce dust, moisture and warm ambient air into the enclosure. Closed-loop cabinet air conditioning keeps internal cabinet air separated from external air while removing heat from the cabinet.

• Protects PLCs, VFDs, drives, power supplies and electronics from high cabinet temperature.
• Reduces dust and humidity exposure compared with open ventilation cooling.
• Improves reliability of control and communication equipment in hot environments.
• Useful for outdoor cabinets where ambient conditions are harsh.
• Supports stable cabinet temperature for automation and monitoring systems.
• Helps reduce unplanned downtime due to heat-related component failure.

Recommended Selection Process

Correct cabinet air conditioner sizing depends on internal heat load, cabinet size, ambient temperature, target internal temperature and installation environment. The cooling capacity should be selected based on real heat load, not only cabinet size.

• Calculate total internal heat load from drives, power supplies, controllers, relays and other installed equipment.
• Confirm indoor or outdoor installation and maximum ambient temperature.
• Confirm required cabinet internal temperature or thermostat setpoint.
• Check cabinet size, insulation, solar exposure and heat gain from surroundings.
• Confirm IP rating requirement and whether closed-loop cooling is required.
• Confirm door strength, cut-out size and available mounting area.
• Confirm power supply, alarm wiring, RS485 communication and monitoring requirement.

Integration with IoTWatt 4.0 and Monitoring Systems

The HPC1000T includes RS485 communication and dry contact alarm output, making it suitable for integration into cabinet monitoring systems, PLCs, BMS, EMS or IoTWatt 4.0. Cabinet cooling alarms and temperature-related status can be used to improve maintenance response and protect critical electronics.

• Connect dry contact alarm to PLC, remote I/O or monitoring gateway.
• Use RS485 communication where supported for temperature and status monitoring.
• Monitor cabinet temperature together with equipment power and operating data.
• Create alarms or maintenance tickets when cabinet temperature rises or cooling fault occurs.
• Use IoTWatt 4.0 to correlate cabinet temperature, power consumption and equipment operation.
