The Phoenix TL400 Lavatory Service Truck is designed to service commuter and narrow body commercial aircraft. It is a self contained module mounted in the bed of a Ford F-250 pickup truck. Phoenix uses a two tank system for lavatory servicing. The waste tank and flush tank are separate components fabricated from 304 stainless steel and are baffled in both directions. A hinged clean-out cover is provided on the waste tank for easy access to the dump valve to remove impediments. The waste tank has a tray to store the waste hose and to prevent spillage of waste onto the top of the unit. The waste hose drain into the waste tank is at a low height of 49” from the ground. The flush system uses a 12VDC electric motor driven pump to dispense the degerm solution. The pump and motor are located in the pump compartment of the service module on top of the waste tank, just ahead of the flush tank. Electrical power to run the pump and the optional 12 VDC heater is drawn from the truck battery. This eliminates the need for adapting to the chassis and engine, and eliminates the need for a hydraulic system.
The TL400 can also be sold as a kit to be installed in approved chassis that meet the minimum GVWR and have sufficient electrical charging capabilities (Ford F-Series pickup 2012+). The TL400 electrical system depends on the use of static engine control to increase alternator output in order to keep the truck battery optimally charged while performing servicing operations.
