Modular Chiller 35-2240 kW Easy-Maintenance Heat Pump
The chiller plant that runs itself so your team can focus on everything else. Featuring 5-year warranty protection for long-term reliability.
Product Overview
Designed for facility managers facing the challenge of maintaining chiller plants without consuming entire maintenance budgets, the Midea Air Cooled Modular Chiller family offers three distinct models: Aqua Thermal (R32), King (R410A), and King Plus (R410A). The modular architecture eliminates single points of failure, with each of up to 256 cascaded modules operating as an independent self-contained unit with its own compressor, refrigerant circuit, and control board.
When maintenance is required on one module, the remaining units continue operating at full capacity. This eliminates plant shutdowns, emergency call-outs, and service interruptions for building tenants. The system covers 35 kW to 180 kW per module, cascading to a total plant capacity of 2,240 kW.
Routine maintenance on any single module takes just 2-4 hours and can be performed while the rest of the plant continues operating. No full-plant downtime, water system drainage, or tenant coordination is required. Enhanced Vapour Injection (EVI) compressor technology maintains rated heating output at -20°C ambient, enabling true year-round heat-pump operation without separate boiler systems.
Key Features
Zero-Downtime Maintenance
Each module operates independently—maintenance on one unit does not affect the rest. In a 16-module configuration, pulling one module reduces capacity by less than 1%, allowing proactive scheduled maintenance without operational disruption.
- Independent module operation prevents cascading failures
- Less than 1% capacity reduction during single module maintenance
- Proactive scheduled maintenance replaces reactive emergency repairs
- No plant shutdown or water system drainage required
- 2-4 hour service window per module
- Eliminates emergency call-out premiums and operational disruption
Simple Control Systems
Designed for general maintenance technicians, the intuitive control system displays total plant status, individual module health, and active alarms in plain language. Automatic lead-lag rotation balances compressor hours without manual intervention.
- Master controller shows total plant status on intuitive interface
- Plain-language status indicators require no specialist training
- Automatic lead-lag rotation balances compressor hours
- Individual module controllers clearly identify faults and required actions
- Optional Smart Cloud mobile app enables remote monitoring
- Reduces after-hours site visits through remote diagnosis
Integrated Heating and Cooling
EVI heat-pump capability eliminates the need for separate boiler systems in most climate zones, consolidating heating and cooling into one platform. This reduces equipment, maintenance contracts, spare parts inventory, and specialist trade requirements.
- One platform for heating and cooling—half the equipment, half the maintenance
- Heating output maintained at -20°C ambient
- Reduces spare parts inventory and maintenance contracts
- No seasonal boiler commissioning or fuel supply management
- Simplified mechanical plant room with fewer systems
Phased Expansion Capability
Start with minimum viable capacity and add modules as building occupancy grows. Each addition is a simple plug-and-connect operation—no system redesign required. Equipment always operates near optimal load, avoiding oversized chiller efficiency penalties.
- Start with minimum capacity—add modules as occupancy grows
- Simple plug-and-connect operation for module additions
- Equipment operates near optimal load for maximum efficiency
- Preserves capital by aligning investment with actual demand
- Team learns system gradually as plant capacity increases
Built-In Redundancy
Inherent N+1 redundancy without dedicated standby units. Loss of any single module automatically redistributes load across remaining units, maintaining 99%+ plant capacity during outages.
- Inherent redundancy without idle standby equipment
- 99%+ capacity remains available during single-module outages
- Automatic load redistribution within seconds
- No capital wasted on idle standby machines
- Real redundancy—always running, always tested, always ready
Predictable Maintenance Costs
Standardized identical modules ensure predictable annual maintenance budgets. One set of spare parts, one service procedure, and one troubleshooting flowchart covers all units across multi-building portfolios.
- Standardized modules across entire plant
- One spare parts set covers all units
- Technician trained on one site can service any site with same system
- 5-year warranty on all major components
- Module-level maintenance prevents cascading cost events
- Annual maintenance budget forecastable based on module count
