Hitachi VM Magnetic-Bearing Centrifugal Chillers

Product overview

VM uses magnetic bearings, a permanent-magnet motor and a direct-drive inverter centrifugal compressor. The oil-free arrangement is distinct from the oil-lubricated VG and geared S series. The tables below retain 19 R134a selection examples, from 200 to 1,100 USRT, with their complete compressor and heat-exchanger references. Final selection starts with the actual chilled-water duty and condenser-water conditions.

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.

Key configuration options

• R134a F-code examples only. R513A and R1234ze(E) options in the nomenclature require their own model selection and ratings.
• Main power: 380 V / 3 phase / 3 wire / 50 Hz; control power: 220 V / 1 phase / 50 Hz. Inverter starting follows the listed configuration.
• Select water-box arrangement, connection direction, pressure rating and plant-room access against the project schedule.
• Manufacturer reference: VM brochure, print code Z0050001-251008. The tabulated references are selection examples, not a stock list.

Applications

• Central chilled-water plants for large commercial buildings and manufacturing facilities.
• Industrial cooling equipment procurement based on the required water temperatures, load and site conditions.

Information for equipment selection

• Cooling duty, load profile and required quantity; complete model reference where known.
• Chilled-water and condenser-water entering / leaving temperatures, flows and water-side pressure requirements.
• Voltage, phase, frequency, starting method and plant-room access / lifting constraints.
• Equipment schedule or BOQ, project location, destination country and requested delivery date.

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.
