Electronics & Software for HVAC and Refrigeration
PRM.DEV helps manufacturers and OEMs bring HVAC products to market faster and reduce delivery risks. We design electronics, embedded firmware, and IoT systems for heating, ventilation, air conditioning, and refrigeration.
Equipment and systems we work with
  • Heating

    Gas and electric heaters, infrared heating systems (baseboard, duct, underfloor), heat pumps and hydronic boilers, unit heaters, thermostats, and control systems.
  • Cooling and refrigeration

    Chillers and evaporative coolers, rooftop and split systems, VRF/VRV, commercial refrigeration equipment, precision cooling for data centres, PTAC units, compressors, and measurement/controllers.
  • Security and alarm systems

    Proactive security: intelligent sensors, continuous monitoring, and instant alerts for fast response and reduced intrusion risk.
  • Control and automation

    Programmable thermostats and BMS/BAS, drives and motor control, temperature/humidity/IAQ sensors, pressure sensors/relays, VFDs and soft starters, PLCs, and I/O modules.
Our services

  • Solution engineering

    Turnkey new products: mechanical engineering and industrial design, custom enclosures, prototyping, design-for-manufacturing, and documentation.

  • Digital transformation and IoT

    Smart devices and gateways, scalable HVAC software, predictive maintenance and data analytics, remote monitoring and control platforms, and BMS integration.

  • Embedded systems and electronics

    Firmware (RTOS, Linux), mobile apps (Android), verification and prototypes, schematics and PCB layout, power electronics and supplies, sensor integration, motor control systems.

  • Manufacturing & lifecycle

    OTA and version control, embedded CI/CD, HW/SW testing, production and supply chain support, plus post-launch maintenance.
