Overview
The Vortec 727-35H vortex cooler is a compressed air–powered enclosure cooler engineered for industrial electrical and control cabinets. Available in NEMA 12, NEMA 4, and NEMA 4X versions, the 727-35H is rated NEMA 4 and suitable for environments exposed to dust, moisture, and splashing water. This model produces a cooling capacity of up to 2500 BTUs per hour with 35 SCFM air flow. It requires no electrical connection, no refrigerants, and no moving parts—making it a reliable alternative to traditional fan-based and A/C cooling systems.
Key Features
- No Moving Parts: Vortex tubes utilize no moving parts, which translate into no maintenance.
- Contamination-Free Cooling: Avoid possible contamination with dirty, humid air caused by fans and maintain a slight positive pressure inside the cabinet to help prevent the ingress of dust and moisture.
- Compressed Air Powered: Uses factory compressed air to create cold and hot air streams; requires a compressed air supply of 80-100 psi.
- Low Operating Cost: Low cost alternative to expensive, high maintenance air conditioners.
- UL Listed: UL Listed with a 10-Year Warranty.
