EVAPCO launched the PuRe-JET™, an innovative pumpless recirculation adiabatic system designed to simplify operation, reduce maintenance and deliver highly efficient thermal performance. By completely eliminating the need for mechanical pumps, PuRe-JET minimizes system complexity while reducing water usage and long-term operational costs.
Make-up water is introduced into the system and directed through EVAPCO’s proprietary pumpless ejector device.
Engineered to respond to changing conditions, PuRe-JET uses a demand-based control strategy. Under standard conditions, the system operates with energy-efficient fans that ramp up as load and ambient temperatures increase. When additional cooling capacity is required, the system activates staged adiabatic assist to maintain precise temperature setpoints.
During stage 1 operation, make-up water is introduced into the system and directed through EVAPCO’s proprietary pumpless ejector device. Using a venturi action, the ejector draws recirculated water from the tank and accelerates it through the system, achieving full adiabatic performance without a pump. This optimized water distribution fully saturates the adiabatic media, lowering the entering air temperature and increasing heat rejection across the coil.
The system is designed for water efficiency by recirculating unused water while managing bleed-off to control cycles of concentration. As thermal demand continues to rise, stage 2 is automatically initiated, following the same sequence of operation to ensure consistent performance under peak conditions.
PuRe-JET represents the next evolution in adiabatic cooling by combining simplicity, sustainability and performance in a single solution.
