Condenserless Chiller with Fixed Speed Scroll Compressor

30WGA

The Carrier AquaSnap® 30WGA is a high-performance condenserless scroll chiller designed for ultimate installation flexibility. By separating the cooling process from heat rejection, the 30WGA allows the main mechanical unit to be protected indoors while connecting to a remote outdoor air-cooled condenser. This makes it the premier choice for urban refurbishments, sites with strict outdoor noise ordinances, or projects where indoor space is premium but water-cooled infrastructure is unavailable.

  • Cooling Capacity: 25 kW to 190 kW (7 to 54 Tons)

  • Configuration: Condenserless (Indoor unit for remote air-cooled heat rejection)

  • Compressor Technology: Multi-scroll design for superior part-load efficiency

  • Refrigerant: High-efficiency R-410A

  • Footprint: Ultra-compact (standard doorway accessible)

Single-Effect Hot Water-Fired Absorption Chiller

The AquaSnap® 30WGA is engineered to solve complex architectural challenges. Unlike traditional "packaged" air-cooled chillers that must sit outdoors, the 30WGA remains in your climate-controlled mechanical room, extending the equipment's lifespan and simplifying maintenance.

  • Optimized for Refurbishment: Its slim profile allows it to pass through standard doors and elevators, making it the perfect "drop-in" replacement for aging indoor chillers.

  • Stackable Space-Saving Design: Features a unique frame that allows two units to be stacked vertically, doubling your cooling tonnage within the same square footage.

  • Enhanced Component Longevity: By housing the compressors and electronics indoors, they are shielded from the UAE’s extreme heat, humidity, and sand, resulting in lower wear and tear.

30WGA

Patented Auto-Adaptive Logic

Features a sophisticated algorithm that optimizes condensing pressure at part-load to reduce compressor work, ensuring a perfect supply of liquid refrigerant to the evaporator.

Dual Time-Schedule Management

The controller supports two independent schedules for automated unit start/stop and "dual set-point" management, allowing for optimized energy use during night or weekend modes.

Intelligent Pump Control

Equipped with variable-flow pump logic that reduces system energy consumption by adjusting water flow based on real-time load, eliminating the need for constant-speed pumping.

Total Unit Protection & Monitoring

The system permanently analyzes suction and discharge pressures and temperatures, automatically adjusting operation to prevent faults and ensure the machine stays within its safe operating map.

What does "condenserless" mean for my installation?

A condenserless chiller like the 30WGA contains the compressors and evaporator but requires a separate remote outdoor condenser. This allows you to keep the loud and sensitive mechanical parts protected indoors while rejecting heat to the outside air.

Can this unit handle hot water production?

Yes. When equipped with the "Built-in DHW" option, the 30WGA can control both your space heating and domestic hot water requirements, acting as a complete thermal hub for your facility.

Is the 30WGA suitable for sound-sensitive buildings?

Absolutely. The entire range is designed for low sound levels. We also offer a "Low-Noise" option that provides an additional -3 dB(A) reduction, making it ideal for residential areas or hotels.

How does the "stacking" feature work?

The 30WGA chassis is designed for vertical stacking (up to size 090). This allows you to install two chillers in the footprint of one, which is a major advantage for high-capacity projects with very limited mechanical room space.
