Job Description:
BASIC FUNCTION Supports the testing of refrigeration equipment,
both for industrial and commercial applications, by working closely
with our Engineering Groups for research and development
activities, as well as our Service Department for field-related
issues. The core focus of this testing facility is to prove out
new, or changes to existing, screw compressor product lines before
they are released for production. Technicians will be exposed to
various refrigeration systems and associated auxiliary equipment
utilized to test these compressors. ESSENTIAL DUTIES &
RESPONSIBILITIES Testing objectives are set by our various
engineering groups and are outlined on a Test Request. This
document includes information such as what is to be tested, how it
should be tested, any special instrumentation requirements,
duration of test, etc. As a technician you must be able to
comprehend what is described in this document and apply that
information to the task at hand. Testing of both open drive and
hermetic compressors are performed, therefore as a technician you
must be familiar with making electrical connections, no voltage
higher than 480VAC 3 phase, and perform motor alignments.
Connections to the compressors are typically comprised of carbon
steel pipes, ranging in size from 4 inches to 16 inches in
diameter. Cranes and other lifting devices are utilized to
manipulate pipework. Small peripheral connections are made with
either hose or rigid tubing. Instrumentation is a key component to
the process. A few of the types of measurements taken are pressure,
temperature, flow, power, and vibration. Several forms of
calibrations are performed in-house. As a technician you will be
required to become familiar with the various forms of
instrumentation and the equipment utilized to calibrate. Systems
will need to be pressure tested, vacuum pulled and then charged
with refrigerant. In this role you will be required to pressurize
systems per our internal guidelines, understand the importance of
and express a firm understanding of proper vacuum techniques and
thresholds, and be able to safely handle and transfer various
refrigerants while complying with company and regulatory standards.
During the testing process this is where a technician will be
required to fully understand how the systems work and be able to
manipulate them to achieve the desired conditions set forth by
engineering. Data collected must meet Test Lab Standards prior to
being passed along. While these topics represent the core of what a
technician is required to perform, other aspects include but are
not limited to: · Material compatibility Testing · Component
testing: valves, transmitters, VFD’s, etc. · Compressor prototype
assembly · System Maintenance · Controls layout and implementation
On the job training will be provided, therefore not all skillsets
related to the various roles and responsibilities are required in
advance. QUALIFICATIONS To perform this job successfully, an
individual must be able to perform each essential duty
satisfactorily. The requirements listed below are representative of
the knowledge, skill, and/or ability required. · Firm understanding
of the refrigeration cycle and its components. · Well versed in AC
and DC circuitry. · Mechanically inclined · Self-driven individual
· Maintains a positive attitude and works well with others
EDUCATION/EXPERIENCE Requires an associate’s degree from college or
technical school; or two (2) to five (5) years related experience
and/or training in refrigeration; or equivalent combination of
education and experience. EPA 608 Certificate preferred. COMPUTER
SKILLS Proficiency in Microsoft Suite Applications (Word, Excel,
Access, and PowerPoint), as well as Internet software and E-mail
are required. PHYSICAL REQUIREMENTS The employee is occasionally
required to lift no more than 50 pounds.
