| |
| Combustion analyzers |
| Useful for field technicians, ECOM EN2 portable combustion analyzers measure oxygen, carbon monoxide, carbon dioxide, nitric oxide, and nitrogen dioxide as well as temperature, stack draft/pressure, efficiency, and excess air. An internal pump and Peltier gas cooler with automatic condensate drain ensure accuracy and longer sensor life. Standard features include an on-board printer, secure digital memory card, and wireless Bluetooth. |
| |
| Kitchen hoods |
| An auto-cleaning kitchen hood that handles grease extraction and filter cleaning, Grease Grabber H2O incorporates a dual-stage filtration system that combines Grease-X-Tractor and the Grease Grabber filter to remove 100 percent of grease that is 5 microns or larger from air streams. This works in conjunction with a solenoid-powered system in the hood that sends hot water mixed with detergent to spray nozzles aligned along the filter banks and plenum area. The mix is recaptured, and a high-efficiency pump recirculates it to conserve water. The system purges and rinses with fresh hot water, eliminating the need to remove and clean filters by hand. |
| |
| Torque wrenches |
| Torqtite adjustable open-end torque wrenches allow all tube and hose ends to be tightened to their correct torque requirements. Developed to compliment Flaretite’s flared seals for 30-, 37-, and 45-degree flared fittings, the wrenches have a low profile and reversible spanner design. The wrenches also are supplied with torque rating tables for common fittings. |

The slim package meets the space requirements of end users, yet has the flexibility to meet the varying requirements of specifying engineers and HVAC designers. |
| |
| Fabric ducts |
| For commercial retrofits and new construction, UnderFloorSox fabric air-dispersion ducts are designed to reduce thermal decay and improve temperature consistency within an underfloor-air-distribution (UFAD) plenum. Twelve to 18 in. in diameter, the ducts are routed through a UFAD plenum to provide even air dispersion and temperature to perimeter, remote, and other high-heat-load zones that typically suffer thermal decays of 6˚F or more. |
| |
| Boilers |
| Water Wall Series boilers have been expanded to reach up to 3.12 million Btu. Listed by a nationally recognized testing laboratory as a complete boiler assembly, the gas, oil, and combination gas/oil boilers can achieve efficiencies of up to 86 percent.
