Hitachi gas-fired absorption chiller configuration
Representative image. Appearance may vary by configuration.

Product overview

Hitachi absorption equipment uses a water / lithium-bromide cycle driven by gas or steam. This page separates gas-fired and steam-fired tables, standard and high-efficiency configurations, enlarged-heating variants and three-use equipment. Compare each heat-source configuration on its own terms: steam consumption and fuel heat input are different from the electrical input of a compressor chiller.

Key technical specifications

Match the complete model and configuration to your design duty. Compare ratings only at the stated water and ambient conditions; then send the model reference, quantity and project requirements for review.

Scroll each table horizontally to compare all columns. Model references remain visible as you scroll.

  • Printed model-header / suffix references only, not complete order codes; final hot-water and domestic-water configuration requires manufacturer selection.
  • Cooling water circuit: chilled water 12 / 7 °C; condenser water 32 / 37 °C. Heating water entering / leaving: 56.4 / 60.0 °C; domestic hot water entering / leaving: 45 / 60 °C. Duties and hydraulic circuits must be selected separately.
  • Auxiliary supply AC 380 V / 50 Hz / 3 phase. The three-use table is not merged into the standard or enlarged-heating tables.
  • Manufacturer reference: Z0050065-251030; physical PDF page 10.

Key configuration options

  • Gas-fired CGN and enlarged-heating CGH references have separate tables; CW identifies the steam-fired configuration in the reviewed brochure.
  • Model references retain the printed header and suffix separately. Final order codes also depend on the selected hydraulic arrangement, heat source and optional equipment.
  • Three-use configurations add a separate domestic-hot-water circuit. Cooling, space-heating and domestic-water duties require individual selection.
  • Confirm available gas or steam conditions, condenser-water duty, water-side pressure and plant-room access before comparing selections.

Applications

  • Large commercial or industrial chilled-water projects with an appropriate gas or steam heat source.
  • Projects requiring separately selected chilled-water, heating-water or domestic-water equipment duties.

Information for equipment selection

  • Gas-fired or steam-fired duty, required configuration and cooling / heating loads.
  • Gas supply or steam pressure / availability, water temperatures, flows and operating schedule.
  • Water-side pressure, auxiliary power, installation access, project location and destination country.

Application suitability requires a review of the project requirements and selected model.

Project equipment procurement

Delta M&E reviews equipment requirements, manufacturer selections and supply arrangements for each inquiry. Send your BOQ or equipment schedule to discuss the required model, documentation and destination.
