Product overview
RMVS uses DC-inverter enhanced-vapour-injection scroll compressors in an air-to-water arrangement. PH and MH references have separate cooling and heating ratings, seasonal indices and hydraulic data. NMW and AMW selections also differ in guards and weight. The tables describe individual modules, so a combined installation needs a separate equipment and water-system selection.
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
- PH and MH are kept in separate tables; RMVS065MH cooling is 66 kW in this brochure, while RMVS065PH cooling is 65 kW.
- 380–415 V / 3N~ / 50 Hz; R32; brazed-plate water heat exchanger. The water pressure drop includes the supplied Y-strainer.
- AMW references include the listed air-side guard; NMW and AMW net / operating weights remain distinct.
- Operating envelopes vary with leaving-water temperature. Selection outside the plotted standard range requires manufacturer review.
Applications
- Commercial air-to-water heating and chilled-water equipment procurement.
- Projects evaluating multiple modules against the required water temperatures, electrical supply and load profile.
Information for equipment selection
- Complete RMVS PH / MH reference, NMW / AMW configuration and module quantity.
- Cooling / heating loads, design ambient conditions, water temperatures, flow and control requirements.
- Power supply, location, acoustic constraints 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.
