2 G R B PA ET USG PA ET B G Vaporizers Algas Zimmer Electric Vaporizers The Zimmer electric vaporizer is a compact, simple and reliable solution for smaller LPG loads where a single storage tank falls short on vaporization capacity. Designed for reliability, there are no switches, thermostats, floats, relays or other electric controls. The self regulating internal heaters will operate with any voltage from volts, single phase. It is light-weight and wall or tank mountable for easy and versatile installation.

The units are Explosion Proof (Class1, GroupD, Division1), and are available in a wide variety of operating voltages for versatile installation options. Economizer Valve The Economizer valve mounts on the discharge of the vaporizer and remains closed until the tank pressure falls to 30 psig. This allows a supplemental bypass pipe to feed the load directly from the tank saving the energy of the vaporizer until required. 1 in and out.

4 Separators Removes heavy ends from gas vapor streams. Especially effective after vaporizers. Single Stage models provide primary extraction of heavy end particles and solid material in a gas vapor stream by centrifugal action in the chamber. Available in Style A Vertical configuration only. All Welded Contruction Designed to be installed in a controlled pressure pipeline, 100 PSIG or less. Self Cleaning Prime Coat Painted Separators Two Stage models provide, in addition to the centrifugal action, a filter element in the chamber for coalescing of fluids suspended in the gaseous state, as well as collecting solids as small as 5 microns.

5 USG G B OUTLET INLET Propane/Air Mixers LP-Gas Standby Systems LP-Gas standby fuel installations provide reliable energy needs during natural gas curtailment. Natural gas supplies are often restricted especially in the winter months when demand on the natural gas mains is at its maximum. The natural gas utilities have a finite supply of pipeline capacity and experience shortages during peak demand days. An LP-Gas standby system allows the end user to switch to a compatible propane/air mixture during natural gas curtailment. The connected plant can continue normal operations with an equivalent clean burning fuel. The plant manager can also gain significent savings in their year-long fuel costs by contracting with the utility for an interruptible natural gas rate. Standby System Plant The layout of a typical standby system plant is depicted showing the major components. Propane Storage Details of the system valving, spacing and distances are intentionally not shown. Storage Tank Truck Unloading Pressurizing Pump Mixer Mixer Pump Truck Unloading Typical Propane/Air Mixing Systems A typical arrangement for a propane/air mixing assembly is depicted. The mixer is a typical venturi style with a mixed gas holding tank and requires a pressurizing pump to provide the elevated vapor pressure for gas/air mixing. All piping, valving and ancillary equipment must be selected and installed according to the provisions of NFPA 58. POWERXP Pump Bypass Line Propane Storage PA ET Mixed Gas Out Pressurizing Pump 117

6 Propane/Air Mixers Algas Propane/Air Mixing Systems The Algas XPV Propane/Air Mixing Systems are complete natural gas replacement units for commercial and small industrial natural gas users. They are a combination of the Power XP Electric vaporizer and the Vaporaire Venturi Air/Gas mixer. The units come completely pre-packaged with vaporizer, venturi arrangement, surge tank and all controls for easy installation. The smaller units utilize a single vaporizer/mixer combination. The larger units use multiple vaporizer/mixers factory connected in parallel to provide greater capacity. All units are Explosion Proof (Class1, GroupD, Division1), and are available in a wide variety of operating voltages for versatile installation options. XPV XPV5 5 Cap MM Inlet Outlet Size (in.)

This prevents the natural gas from entering the mixed gas lines and the mixed gas from entering the natural gas lines. The respective gas regulators aid in preventing back flow but should not be depended on as the sole devices left to provide this function.
