Complete installation services are available from our offices, including walk-in erection, internal electrical, and refrigeration installation. We have experience all around the country and employ teams, and factory personnel qualified to perform these special services. Depending on site considerations, both union trade and qualified non-union labor are provided.

Complete shop drawings are forwarded during submission time, and operation and maintenance documents as well as as-built drawings are provided. Generally, performance and validation testing is available as well.

Insulted-Structures™ is a unique product. It is essentially a prefabricated “kit” requiring assembly in the field. In this sense, it is actually an “unfinished goods” when leaving the factory, until installation in the field has been performed. Installation of the insulated panels is predominantly performed by out trained factory installation crew. The usual procedure is for the install crew to arrive with the shipment from the factory, complete the unloading, and bringing the panels to the various locations on the job site where they are to be installed. On larger projects, our sales engineers often make pre-inspections of the job site, confirming field dimensions and answering related questions.

Erection of the walk-in portion of the project then begins. Floors, walls and ceiling are locked together with our internal strapped cam lock system. Doors are hung, checked for level and operation. Penetrations are made as required in the field for ventilation ducting if required.

Refrigeration work then begins. We mount the evaporator coils onto the underside of the ceiling of the walk-in, mount the condensing units in their prescribed location and begin the refrigerant piping runs to link the systems. On some projects, we pre-pipe the refrigerant tubing, stubbing out to later complete the installation. This is done when there are longer line runs, or concealed access areas which have to be handled earlier in the project. Once attached, refrigeration lines are leak tested according to the specification requirements.

Electrical work, which pertains to the internal wiring of the refrigeration controls is then begun. We hang lighting, mount probes, run conduit, pull wiring, perform electrical testing and mount the control panels on the face of the walk-in, (or in other predetermined locations). The control panels are constructed in our UL approved controls shop, and carry a UL 508 rating with serial numbers. This makes local inspections follow through without any code issues.

Refrigeration systems are then charges with refrigerant and the units are started up and tested. Note: power feeds to the condensing units, (electric) and water connections for water cooled units are performed by the GC on the job. After running through standard checklist items, an installation report can be generated for validation purposes.

Performance testing, if specified, is then performed. This usually consists of a strip chart recorder with 16 probes mounted in various locations in the walk-in to test the performance of the room in accordance with the specifications. A complete test report relaying the results is then presented to the owner’s representative. Operation and maintenance manuals and as-built drawings are then produced and are turned over to the owner.

OUTDOOR REFRIGERATED BUILDING INSTALLATION

For projects where refrigerated buildings or stability chambers are to be constructed outdoors, we can offer a complete turn-key service. This would include architectural plans suitable for building permits, engineering drawings to comply with local codes, and detailed work scope proposals to allow budgeting and contract documents to be formed.

Outdoor structures require construction foundations. The detail of the design varies with the site situation, ground composition and whether cooler or freezer application. We then excavate, set forms, pour footing and foundation walls, install insulation below grade; install ventilation systems, and/or below grade frost prevention systems as required.

Larger structures call for internal steel frameworks, which we design and erect on site. This is specialty construction, as thermal transfers and vapor seal integrity are important factors in refrigerated structures.

Insulated panels are then delivered and erected around the perimeter steel framework. Special attachments are made to the steel to enable thermal bow and expansion forces to function unimpeded by the steel. Any height structure can be accommodated. We have built a structure as high as 56’ for the Pepsi Cola company to house their storage tanks.

Weather roofs are then installed, according to the specifications. The majority of installations are fitted with membrane rubber or PVC roofing. Pitched roofs are available, although flat roofing is normally the desired design for reasons of efficiency.

Refrigeration work then begins. On large installations, the condensing units are normally placed on grade and piped to the internal evaporators. Cosmetic coverings hide the refrigerant tubing and condensate drain lines. After electrical work has been completed, the systems are started up and tested. Our structures are Factory Mutual rated and are classified as a Class One building. The insulated panels carry our 15-year manufacturer’s warranty.

Whether it’s a simple 10’x10’ room, or a refrigerated warehouse the size of a football field, Insulated-Structures™ can provide complete installation services to give you one point of contact on your project.

SERVICE

After the installation is complete and everyday use begins, there may be adjustments and service required of the equipment. For warranty service, first contact the sales- engineering office. We can usually diagnose the problem and may be able to solve the issue on the telephone. If a field visit is required we dispatch a member of the installation crew to make any necessary repairs or replacements. This work is covered under the warranty details spelled out in your contract. On larger installations we provide 24-hour service numbers, which can dispatch technicians depending on the details of the problem.
