Fuel immersion heater assembly with low fuel shutoff switch. Fuel tank monitoring panel - wired to fuel tank connections. Fuel tank annuciator panel - wired to fuel tank connections. Combination low/high level float switch assembly with 1/2" NPT electrical connection for fuel pump start-up control. UL rated lift lugs capable of lifting the entire package (gen-set, enclosure and tank) OPTIONAL: On heavy weight gen-set packaged assemblies, tanks are placed in a structural I-beam base skid with 4 lifting lugs that are designed to lift the entire gen-set packaged assembly. ACS can fabricate tanks of 304 or 316 L stainless steel material.

The Fuel Maintenance System (FMS) is a fully automated, stand-alone, self-contained system designed for tanks of varying sizes. It cleans and reconditions stored fuels, eliminating the problems associated with the water, sludge and other contaminants that develop in fuel storage tanks over time. The system’s automatic cleaning program will provide a constant clean fuel supply that will assure the reliable operation of your emergency power unit whenever it is needed. The FMS is operated by a 6” color touch screen PLC/HMI or a basic LCD PLC controller, will periodically circulate your stored fuel through a series of water removal and particulate filters that remove 99.7% of free water and 99.5% of particulate contaminants. It will keep your stored fuel in clean, like new condition, preventing clogged engine filters, injection system repairs and the need for periodic fuel replacement or tank cleaning due to fuel contamination and the resulting degradation. ​ The system is fully monitored and alarmed for safety.  Alarms can be sounded at the unit or communicated off site via a MODBUS (RS 485) serial and Ethernet TCP/IP connection. Two (2) dry contacts for pump running and common alarm are available for customer use.  The system will alarm and can be shut down automatically for any or all of the following conditions: ​ 1.  Hi-pressure at the primary and final filters, indicating a filter change out is needed 2.  Hi-vacuum at the water separator, indicating the separator needs service. 3.  Hi-water in the separator, indicating the need for it to be drained. 4.  Equipped with an in-cabinet drip tray, a leak detector in the tray will sound an alarm and shut  the system down on detection of any liquid, which may indicate an internal system leak. ADDITIONAL FEATURES UL 508A Labeled Control Panel Push button emergency stop located on the outside of the cabinet (remote mount is optional) 3 Position selector switch, Pump-Hand / Off / Auto Control logic short circuit protection, 1 A / 1-Pole

ACS Acoustical Enclosures (standard and custom) are designed to control noise levels of engine driven sets, compressor, and pump systems.  The performance of a standard enclosure will reduce the equipment's noise level to 85 dBA or less, 3 feet from the enclosure and 5 feet above grade level.  Enclosures can be custom designed to reduce equipment noise to meet virtually any sound level required. ​ ​We also offer upgrade options on construction materials, wind load ratings, seismic ratings, sound attenuation and the ability to add off-shore paint or electrical components. GENERAL ENCLOSURE CONSTRUCTION: Materials of Construction: Materials will be properly selected for the type of environment and service life the unit will require. Normal materials of construction for the walls and roof skin, framing and inner liner include aluminum, stainless steel, galvanneal steel.  As well as other materials required to meet arctic conditions. Skin: Material thickness ranges from 16 gauge to 1/4 plate. Perforated inner liner thickness ranges from 24 gauge. Galvanneal steel is standard. Framing: Structural channels, beams, and tubing consistig of carbon steel, stainless steel or aluminum. Insulation Fill Material: 4 to 8 lbs/cu. ft. density wool, with 4 lbs. beig standard.
