HVAC Controls - Refrigeration and HVAC

Marine HVAC and refrigeration controls regulate temperature, pressure, humidity, compressors, fans, valves, pumps, alarms and defrost cycles. They may be supplied as standalone controllers, PLC-based control panels, sensors, actuators and communication modules for vessel climate-control systems.

ProShipWorks provides end-to-end support to source and supply HVAC Controls for marine vessels, ship operators, industrial facilities, maintenance teams and procurement departments.

Standards, Certifications & Class Approval

Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.

Applicable Standards & Certification	Applicable requirements may include IEC 60945 for marine navigation and radiocommunication equipment where relevant, IEC 60092-504 for special features of marine electrical installations, IEC 60533 for electromagnetic compatibility, and IEC 61131-2 for programmable controllers. Exact compliance depends on the complete marine system and installation.
Class Approval	DNV, ABS, Lloyd's Register, Bureau Veritas and ClassNK may approve marine HVAC control panels or complete systems when submitted under the applicable vessel rules. Individual commercial controllers are not necessarily class-approved; verify the product certificate and project type-approval requirements.

Installation, Maintenance & Safety Information

Installation Notes	Install in an enclosure suitable for the vessel environment, with correct power supply, circuit protection, grounding, cable segregation and ingress protection. Connect sensors, actuators and communication wiring according to the manufacturer manual. Configure refrigerant, control limits, alarms and fail-safe functions during commissioning.
Maintenance Tips	Inspect terminals, cable glands, sensors and enclosure condition during planned maintenance. Verify sensor calibration, alarm operation, controller settings and communication networks. Keep ventilation paths clean and retain an approved backup of configuration parameters.
Safety Notes	Isolate and lock out electrical power before servicing. Follow refrigerant handling regulations and avoid bypassing pressure, temperature or emergency shutdown protections. Use marine-rated components and observe hazardous-area requirements where applicable.
