Each part of the top The Micro in the Voyager Units has built- (three pieces) overlaps in such a way in anti-short-cycle timers, time delay that water cannot leak into the unit . relays and minimum ''on'' time controls. These overlapped edges are gasketed These controls are functions of the Micro and sealed to ensure superior water and are factory tested to assure proper integrity. Compressors operation. Quick- Access panels reduce the Voyager contains the best Scroll The Micro softens electrical ''spikes'' by number of possible water entry points. compressor technology available, in staging on fans, compressors and order to achieve the highest heaters. For added water integrity, Voyager has performance possible.

Features and Benefits Figure 2 - Idler arm assembly Ease Of Installation Power factor of the fan motor is corrected and inrush current is very low Voyager Units provide many time and thanks to progressive fan ramp up start money saving features. (by default: 1 minute ramp up time). Conversionless Units Reduced maintenance costs with: The dedicated design Units (either Almost no maintenance direct coupling downflow or horizontal) require no compared to belt drive. panel removal or alteration time to convert in the field. Easy commissioning with adjustment of nominal airlfow and ramp up time for Horizontal Units come complete with progressive textile duct inflation.

Since Single Side Access it is simpler in design, it is easier to diagnose. No more than three screws must be removed to access components. Reliatel trane 's Idler Arm Assembly Reliatel requires no special tools to run the Voyager unit through its paces.
