In some case you could be eligible for SCS exchange program offering a very quick turnaround. Trusted Compressor Overhaul and Rebuild Company. SCS tear down table has a building oil rail drain to catch all oil drain from compressor during disassembly so there is no oil on the floor that may cause slip and fall. PPE is always available for everyone. Safety training are done year round — safety certifications is required to work in the job site. Frick RWF oil-injected screw compressors: Engineered and manufactured to meet industrial refrigeration requirements. Designed to assure reliability, accessibility, and ease of service. Compact package allows reduced engine room size and lower construction costs. High stage and booster applications for all common refrigerants. Frick compressors perform at peak efficiency under varying loads and operating conditions. Volumizer Variable Volume Ratio Control adjusts the compressor volume ratio during operation to the most efficient point, depending upon system requirements. This reduces energy waste caused by under- or overcompression. Frick compressors allow close system control under widely varying load conditions. This will eliminate that dreaded down time of waiting for your primary or backup compressor to be repaired. If SCS has your down compressor in stock and your exchanged compressor is in repairable condition you may qualify for this program. Please contact SCS to find out more information about this program. The first requirement of the compressor foundation is that it must be able to support the weight of the compressor package including coolers, oil, and refrigerant charge. Screw compressors are capable of converting large quantities of shaft power into gas compression in a relatively small space and a mass is required to effectively dampen these relatively high-frequency vibrations. Firmly anchoring the compressor package to a suitable foundation by proper application of grout and elimination of piping stress imposed on the compressor is the best insurance for a trouble-free installation. Use only the certified general arrangement drawings from Frick to determine the mounting foot locations and to allow for recommended clearances around the unit for ease of operation and servicing. Foundations must be in compliance with local building codes and materials should be of industrial quality. The floor must be a minimum of 6 inches of reinforced concrete and housekeeping pads are recommended. Anchor bolts are required to firmly tie the unit to the floor. The shims should be placed to position the feet roughly one inch above the housekeeping pad to allow room for grouting. An expansion-type epoxy grout must be worked under all areas of the base with no voids and be allowed to settle with a slight outward slope so oil and water can run off of the base. When installing on a steel base, the following guidelines should be implemented to properly design the system base: Use I-beams in the skid where the screw compressor will be attached to the system base. They should run parallel to the package feet and support the feet for their full length. The compressor unit feet should be continuously welded to the system base at all points of contact. The compressor unit should not be mounted on vibration isolators in order to hold down package vibration levels. When installing on the upper floors of buildings, extra precautions should be taken to prevent normal package vibration from being transferred to the building structure. It may be necessary to use rubber or spring isolators, or a combination of both, to prevent the transmission of compressor vibration directly to the structure. However, this may increase package vibration levels because the compressor is not in contact with any damping mass. The mounting and support of suction and discharge lines is also very important. Rubber or spring pipe supports may be required to avoid exciting the building structure at any pipe supports close to the compressor package. It is best to employ a vibration expert in the design of a proper mounting arrangement. See Allowable Flange Loads table. Main oil injection valve may be open too far. Bearing damage or excessive wear. If motor or compressor have been reinstalled, check that installation done according to Slide stop indicator rod stuck. Contact Frick Factor or Frick service for assistance. Compressor must be running with sufficient oil pressure. Slipper seals worn out or damaged. Check that service valves are open. Filter cartridges may be blocked. Check PSID across filters. Strainer may be blocked. Oil pressure regulator set too low or stuck open. Make necessary adjustments or corrections. Black oil leaking from this vent indicates oil seal wear or failure. If leakage exceeds normal allowable rate of 7 drops per minute, replace seal. Set main oil injection and oil pressure for maximum head pressure condition. Oil is too cold. Allow oil to warm up and check again. Service valve on filter outlet is partially closed. Refrigerant carryover or liquid injection overfeeding, correct operation. Loss of suction superheat. Contaminated oil, damaged or not seated coalesce filter elements. Replace oil charge and coalesces. Coalesce return valve closed. Coalescing oil return line strainer blocked. Suction check valve bypass valve open too far to meter flow. Coalesces loose or not seated properly. Economizer check valve not in automatic position or manually opened. Place in auto position. Test and replace if necessary. Valve may be closed. Open hydraulic service valves. Solenoid spool may be stuck or centering spring broken. Check outputs 2 and 3 and fuses. Check LED on coil. If lit, there is power to the coil. Push A side to confirm unload capability. If valve works, problem is electrical. Dirt inside solenoid valve preventing valve from operating both ways. If lit, valve is functioning mechanically. Solenoid service valves may be closed. If slide stop will not move mechanical problems are indicated. Consult Frick factor or Frick service. With 38 models ranging from 71 CFM to CFM, frick gas compressors are available for almost every industrial refrigeration need. The Frick Compressor Package, which features rotor designs that provide the strongest, most efficient operation for their applications. These Frick compressors are designed for use with ammonia, halocarbon, and hydrocarbon refrigerants. The easily manageable, compact package gives you more space and lowers construction costs to save you money. Manufactured to meet your specific requirements, the Frick Compressor Package is reliable, accessible and easy to service.
