Model 2645, 2635 & 2646
One Size Fits All
Sleek and quiet, these new Prime Inline water chillers feature higher BTU compressors and a larger condenser that allows higher air flow and more efficient cooling. The slender shape and small footprint of the Prime Tower chiller allows them to fit under almost any size aquarium and preserves precious space.
Cooler By Design
Squeezed under the housing is a high BTU Matsushita compressor and fan that efficiently chills water while keeping silence a virtue. The black molded housing blends well into any decor. Recessed handles make moving and lifting easy.
The Titanium Edge
Corrosion resistant titanium heat exchanger backed by a lifetime warranty offers the peace of mind you've always wanted. The custom molded evaporator is completely insulated and is configured to provide maximum exposure to the titanium coil - simplicity at its best.
Integrated Thermostat
Digital dual stage controller on 1/15-1/2 hp units automatically controls the water chiller and rear-mounted heater port (heater not included.) Simple keypad programming display with constant temperature readout accurate to +/-1°F.
What's Included
Each chiller includes an integrated digital temperature controller (temperature range 50°-80°), inlet/outlet fittings, 6 ft. power cable and instructions. Digital temperature controller features adjustable temperature differential and programmable calibration mode. All 1/15-1/3 hp chillers use R-134A refrigerant, larger models use R-22. One year warranty.
