Air-cooled chillers
Incorporating advanced variable-speed-drive technology with screw compressors — an industry first — Latitude offers best-in-class energy efficiency and what is said to be the lowest total cost of ownership and quietest operation of any air-cooled chiller. Utilizing HFC-134a refrigerant and available from 150 to 260 TR, Latitude provides full-load design efficiencies as high as 10.3 EER, exceeding ASHRAE Standard 90.1. Integrated part-load values as high as 15.2 EER deliver average annual energy savings of 15 to 25 percent, compared with traditional air-cooled chillers. During acoustically critical morning and evening hours, Latitude chillers are up to 6-dBA quieter (50-percent perceived-noise reduction) than competitive chillers. Latitude units take advantage of SilentNight control, which employs a load-limit control function to ensure quiet operation. Also, they come with built-in acoustic features that eliminate the need for additional sound attenuation and sound-barrier walls.

Chilled-water air conditioner
Designed to provide economical, year-round comfort, the Q-Tec QC Series chilled-water air conditioner provides cooling, dehumidification, and ventilation. Its Quiet Technology allows it to be installed inside structures, eliminating the need for outdoor condensing units or roof-mounted equipment. An optional hot-water coil is available.

Zero-water-consumption urinals
Shown to be more hygienic than their flush-style counterparts, zero-water-consumption urinals from Falcon Waterfree Technologies save an average of 40,000 gallons of water per year. Because there is no flushing mechanism, mechanical maintenance is eliminated. A cartridge with biodegradable sealant provides odor-free operation.

Superheat accessory head
The ASH3 Superheat Accessory Head for digital multimeters measures suction-line pressure and suction-line temperature simultaneously and calculates superheat for both R-22 and R-410A refrigerants. Included with the accessory head is the ATC1 Pipe Clamp Thermocouple.

Equipment-mounting supports
With a high load-bearing capacity attained with a system of internal bulkheads welded into position at specific intervals along their rails, TEMS-1, TEMS-2, and TEMS-3 equipment-mounting supports make roof installation of HVAC units easier. Standard construction includes a welded 18-gauge galvanized-steel shell, base plate, and counter flashing and a factory-installed wood nailer.

Sine-wave filters
MTE Series A sine-wave filters provide a sine-wave output voltage when driven from PWM inverters with switching frequencies from 2 to 8 Khz. For drive applications, they eliminate motor-insulation failures and reduce electromagnetic interference.

Humidity/temperature transmitter
The EE22 humidity/temperature transmitter features interchangeable sensing probes that store calibration data. In extreme temperatures (-40 to 176 F) or where space is limited, the probes can be connected with cables without affecting the EE22's performance.
