Ship Calorifier

ZDR-0.12 Ship Calorifier | Dual-Power Electric & Steam Hot Water Heater for Ships & Offshore Platforms

Product Overview
The ZDR-0.12 Ship Calorifier is a compact, high-efficiency hot water heating system designed for marine and offshore applications. This dual-power calorifier provides flexible heating options using either electric elements or steam, ensuring reliable hot water supply for crew accommodations and service facilities. Certified by major classification societies, it delivers automatic temperature control and safety compliance in a space-saving design ideal for vessel integration.

Key Applications

Crew accommodation hot water supply for showers, lavatories, and sanitary facilities
Galley and kitchen hot water systems on commercial vessels and offshore platforms
Marine sanitation and cleaning water heating
Integrated hot water systems with freshwater pressure tanks
Offshore platform accommodation services with flexible heating options

Operating Principle – Intelligent Heating System
The ZDR-0.12 Marine Calorifier integrates seamlessly with your vessel’s freshwater pressure tank system. Fresh water is automatically supplied to the calorifier and heated through either electric or steam heating elements, then distributed throughout the vessel. The system features comprehensive automation and safety controls for reliable operation.
