Which building types does this unit serve?
The 12 ton heat pump chiller is sized for light commercial and institutional buildings where heating and cooling loads fall in the 30 to 50 kW range. Typical applications include: hotels and guest houses (central heating, cooling and domestic hot water), office buildings (fan-coil or AHU-based climate control), restaurants and retail (heating, cooling and kitchen hot water support), clinics and medical facilities (temperature-controlled environments), schools and public buildings, and light industrial facilities requiring process heat or cooling below 100 °C. The unit is particularly suited to retrofit projects where an ageing gas or oil boiler system is being replaced, since it can connect to existing hydronic distribution. For new construction, it can be specified as the primary plant from the design stage. An EXINDA reference: a commercial boiler-room retrofit in Milano replaced gas boilers with Exinda heat pump chillers (attributed to EXINDA). For buildings with larger loads, the 24-ton unit provides double the capacity, and multiple units can be configured in cascade.
How does it integrate with hydronic distribution systems?
The unit produces hot or chilled water that feeds into the building's hydronic network. Compatible distribution systems include: fan-coil units (two-pipe or four-pipe configurations), air handling units (AHUs) with heating and cooling coils, underfloor heating loops, domestic hot water production via external plate heat exchangers or storage tanks, and process heating or cooling loops for light industrial applications. Flow and return temperatures are adjustable through the unit's controller to match the specific distribution system requirements. For buildings with simultaneous heating and cooling demand (common in hotels and mixed-use buildings), the system architecture may require a buffer tank or thermal storage strategy, which CENTRO-GAS specifies as part of the system design.
What is the business case for a commercial heat pump chiller?
The financial case rests on three factors. First, operating cost: heat pumps deliver roughly 3 to 4 times more thermal energy than the electricity they consume, which translates to significantly lower energy bills compared to gas or oil boiler systems, especially as energy prices rise. Second, a single unit replaces both a boiler and a chiller, reducing equipment cost, plant-room footprint and maintenance contracts from two systems to one. Third, ESG and compliance value: zero on-site combustion, low-GWP refrigerant (if R290 or R32 variant is specified) and high seasonal efficiency support ESG reporting, green building certification and tender eligibility for public and institutional projects. CENTRO-GAS prepares a project-specific ROI analysis based on the building's actual consumption data, tariffs and existing plant, rather than generic projections.
European voltage adaptation and project-specific configuration
The standard unit is manufactured for EXINDA's global platform. For the Serbian and broader European market, voltage adaptation to local three-phase standards is available on request. CENTRO-GAS coordinates the specification with EXINDA's EU service and engineering center in Italy, which provides dedicated engineers for market-specific requirements. Project-specific configuration may also include: hydraulic interface customisation (connection sizes, pump group integration), controller protocol selection (Modbus, BACnet) for BMS integration, and noise attenuation options for urban or noise-sensitive installations.
Why CENTRO-GAS as the commercial heat pump partner?
CENTRO-GAS is not an importer that sells boxes. The company manufactures, installs and services industrial burners and heat systems, and brings that engineering depth to commercial heat pump projects. The offer for commercial customers includes: site survey and load analysis, system specification including hydronic integration design, installation by an in-house technical team with industrial heating experience, commissioning with documented performance verification, and maintenance contracts with defined service levels. EXINDA provides the factory-backed product: 60,000 m² production facility, 90,000 units annual capacity, 100% in-line quality control, 5 enthalpy laboratories, climate testing from -35 °C to 60 °C, CE and ErP certification, and an EU service center in Italy. For resellers, CENTRO-GAS offers product training, installation and service education, and commercial terms that scale with volume. The exclusive EXINDA distribution for Serbia means a controlled channel, not an open market with price erosion.
