Heating Hot Water is supplied at a standard 180°F and is recirculated through the building system by use of centrifugal pumps which are sized to meet specific building requirements. The Model HTS provides Air-free, Hot Water at a con-trolled flow rate, while automatically refilling under nor-mal system losses. Also, the HTS allows for system ther-mal expansion/compression based on the building system volume. A UL-Listed, Industrial Control Panel with sin-gle-point power connection is pre-wired to all electrical field devices and power sources. The Model HTS speeds installation and start-up of building hydronic heating sys-tems which provides significant savings to contractors, engineers, and building owners. www.envirosep.com • ASME, Shell & Tube Heat Exchanger - U-tube, with U-stamp • Base-mounted, End-suction Pumps • Vortex Air Separator, with Auto Air Vent • Bladder Expansion/Compression Tank • Triple Duty Valves & Suction Diffusers • UL Listed NEMA 12 Industrial Control Panel • Float & Thermostatic Steam Trap • Supply/Return Thermometers • Safety Relief Valve • Make-up Water Assembly • Pump Differential Pressure Gauges • ASME Section IX Welding Options: • PLC System Controller w/ Touch Screen • NEMA 7/9 Explosion-proof Rating • Flexible Pump Connectors • Seismic or Vibration Isolators • Plate & Frame Heat Exchangers • Vertical Inline Centrifugal Pumps • Combination Air & Dirt Separator • Specific Performance Criteria (Upon Request) Unfired Pressure Vessels Pressure Piping Model # HTS P.

KEY: [A] = Model # (BTU/hr) [B] = # of pumps (1,2,3,etc.) [C] = Parallel (P) or Stand-by (S) pump designation [D] = Manual (M) or Automatic (A) alternation for multiple pumps GENERAL - This package shall be factory assembled with pump(s), heat exchanger, hydronic accessories, shell and tube heat exchanger, fabricated steel frame, interconnection piping( welded per ASME Section IX certified welders), UL-listed Industrial Control Panel factory wired for single-point field connection per NEC, (and including Condensate Steam Trap). PUMPS-Pump(s) shall be single, end-suction type with radically split, top center-line discharge, self-venting casing. Pump construction shall be cast iron, bronze fitted and shall be fitted with a long-life, product lubri-cated, drip tight mechanical seal, with O-ring seat re-tainer. Impeller shaft to be 416SS fitted with a SS shaft sleeve and be supported by two heavy duty ball bear-ings. The design shall allow back pull out servicing, enabling the complete rotating assembly to be removed without disturbing casing piping connections. The pump shall be mounted on a rigid, single base plate and by flexible with guard to the motor. Seal shall be rated for continuous duty at 270oF, motor shall be open drip proof, NEMA MG-1 with 1.15 service factor HEAT EXCHANGER - Heat exchanger shall be shell and tube type with removable tube bundle. Shell is carbon steel with cast iron heads and tube sheets. Tubes are ¾” OD copper. Unit is rated for 150 psig at 375 oF. Shell-side connections 4” and larger are 150 lb. ANSI flanges and all 3” and smaller are NPT connec-tion. Unit shall carry U-1 form and have ASME stamp for 150 psig operation. AIR REMOVAL EQUIPMENT- System shall in-clude one tangential air separator with internal stainless steel collector tube. Connections to be flanged with a rating of 150 psig. System shall be equipped with ¾” Pressure Relief Valve, ¾” Pressure Regulating Valve, ASME Compression / Expansion Tank (sized by or provide system volume and temperature difference), and tank fitting, sight glass, and tank drain connections to tank. TRIPLE DUTY VALVE- System shall include, on the discharge of each pump, a combination valve incorporat-ing three functions in one body: tight shut-off, spring closure type silent non-slam check, and flow measured/throttling. Valve body shall be ductile iron with two ¼” NPT connections on each side of the valve seat. The valve disc shall be bronze plug disc type with high impact engi-neered resin seat to ensure tight shut-off and silent check valve operation.
