2 Since its founding in 1983, Refrigeration Valves and Systems Corporation (RVS) has become the customer preferred supplier of innovative industrial refrigeration products including factory assembled, packaged recirculation systems and ASME pressure vessels of all types and sizes. RVS was acquired by EVAPCO, Inc. in 1994. EVAPCO is recognized as the leading supplier of quality heat transfer equipment to the Industrial Refrigeration, HVAC, and Process Cooling Industries. The success of EVAPCO/RVS has been the result of a continual commitment to product improvement, quality workmanship, and a dedication to providing unparalleled customer service and satisfaction. Pressure vessels and recirculator packages are manufactured to ASME requirements in two modern facilities located in Bryan, Texas and Taneytown, Maryland. With 90,000 square feet of manufacturing area, EVAPCO/RVS has the capacity to handle all of your vessel and recirculator package requirements. From the smallest pressure vessel to the largest packages, EVAPCO/RVS is committed to providing superior technical support and the highest quality products with fast, on-time shipments to meet your construction schedule. © EVAPCO,INC. 2000 The SRS: Seal-Free Recirculator Solution In today’s industrial refrigeration systems, a premium is placed on operational reliability, value-added features, and reduced maintenance requirements. As regulations governing refrigerant emissions increase, end-users are focusing more resources on reducing the potential for refrigerant leaks. The SRS Recirculator Package is engineered to solve these challenges with the ultimate in reliable, zero-leakage pump technology and troublefree maintenance. The SRS Recirculator Package takes factory-assembled recirculators to a higher level and reflects EVAPCO’s dedication to the continual pursuit of improving product quality and dependability. The SRS Advantage: EVAPCO extends an EXCLUSIVE 3-YEAR WARRANTY on each SRS Recirculator Package. Additionally, EVAPCO carries a complete inventory of pumps and parts to guarantee immediate availability of components in the unlikely event of a problem. All SRS Recirculator Packages are manufactured in accordance with ASME BPV Code Sec. VIII Div. 1, ANSI/ASME B31.5, ASHRAE-15, IIAR-2, and include the following features: Advanced Refrigerant Pump Technology • Featuring Buffalo ® refrigerant pumps, with over 40 years design and application experience. • Hermetically sealed, zero-leakage pump eliminates refrigerant emissions. • Absence of mechanical seals reduces maintenance requirements and costs. • No complicated protective electrical controls required to safeguard warranty coverage. • Very low NPSH requirements ensure reliable, cavitation-free operation. • Totally enclosed, liquid cooled motor with 316SS construction on all wetted parts. • Balanced, self-lubricating conical bearing design provides service life up to 50,000 hours. • Concentric axial wear pattern on bearings inhibits radial movement of shaft and prevents rotor from impacting stator. • Patented variable flow orifice imparts balanced axial thrust loads on bearings. • Self-venting, vertical centerline discharge simplifies piping and pump-downs. Finished Package Features • Standard stainless steel condensate drain pan for pumps reduces corrosion and improves equipment room cleanliness and safety. • Simplified refrigerant piping for easy access for insulation and maintenance functions. • Reduced height on horizontal units for lower shipping costs and one-piece rigging operations. • High quality surface preparation and primer application. • Dried, nitrogen blanket charged, and sealed before shipment.
ASME Accumulator • Designed and constructed for 150 psig, option for 250 psig. • National Board registered. • Increased shell length for maximum system surge volume. • Dual relief valve assembly with 3-way selector valve (shipped loose). • Sized for low refrigerant velocity to prevent liquid carryover to compressors. • Internal recirculation and vent lines reduce insulation cost and protect against shipping damage. • Stainless steel nameplate bracket and standoff. Liquid Level Control • Electronic level control with 3 easily adjustable set points. • High level float switch for positive compressor protection. • Low level shut down to prevent pump cavitation. • Five visual liquid level indicators with frost extensions. • Option available for factory mounting of liquid feed assembly. ASME Oil Pot with Relief • Low side oil recovery without system shutdown. • One common drain point for all low side oil recovery. • Standard stainless steel drain pan. Additional Options: NEMA-4, UL Listed Control Panel • Main circuit breaker disconnect. • Integral control power transformer. • Integral starter contactors. • Protection against pump motor overheating. • Factory mounting and wiring available. Factory Installed Insulation • High quality Styrofoam ® insulation. • ASJ vapor barrier. • 0.030” thick PVC jacketing. Galvanized Steel Base Available Custom Seismic Designs Available 3
