Dedicated to Providing Quality Technical Services to the HVAC Industry

Services

SVL's highly experienced field service staff is the final key component in our customer support program. Check, test, start, first-year warranty work and 24-hour emergency service are always carried out expertly, efficiently and on-schedule.

Each field representative mans a fully-equipped service vehicle and is headquartered out of one of our field service shops to provide the quickest, most reliable service available. And, our far-reaching service capabilities are further enhanced by the use of an electronic fan balancer, clean room particle counter and octave band analyzer, making Schwab Vollhaber Lubratt the only air conditioning service organization in the area to offer these highly technical services.

More than merely startup and repair personnel, our field service people are highly qualified to instruct and consult customers on equipment use and maintenance. And, they also provide feedback to manufacturers on suggestions for product improvement.

Balancing

The specific features of SVL Dynamic Balancing Service are:

• A thorough preliminary analysis of the machine's vibration characteristics to confirm the presence of unbalance.
• Recording of initial unbalance reading, amplitude and phase angle for each bearing location on the machine component.
• Recommendation of appropriate trial balance weights and their locations.
• Calculation of final correction and trim balance weights to achieve acceptable level of rotor balance.
• Recording of rotor response characteristics to allow balancing in one run should subsequent balancing be necessary at a later date.

SVL can perform Dynamic Balancing on single plane, two plane, and multiplane rotors with up to four supporting bearings and four correction planes. In addition, a "best fit" balance can be calculated for vertical and horizontal readings and for up to four operating speeds. Rotors can be balanced above or below their shaft critical speeds.

Diagnostics

Even with well established client maintenance programs, there may be vibration problems that plant personnel have difficulty analyzing. The solution may be as near as the SVL Service office. An experienced analyst will be dispatched to your site to record vibration and machinery operational data. An on-site evaluation of the problem can be provided in most cases. Where more detailed analysis is required, SVL's in-house staff has sophisticated data analysis and evaluation techniques to get positive results.

SVL Diagnostic Service includes a complete written report of the problem and recommendations for corrective measures. This means an efficient and cost effective resolution of your machinery vibration problem.

Solving difficult machinery vibration problems requires modern technology, experienced personnel and old fashioned commitment to meeting the customer's needs. SVL provides all of these element when a field service technician works on your vibration problems
