Expansion Tanks and Vessels are a critical part of a heat transfer system. Improperly designed and installed expansion tanks can cause a variety of system complications. Expansion tanks should be mounted without restriction at the highest part of the piping system and should remain un-insulated as the expansion tank should not be subjected to fluid at elevated temperatures. In addition, these tanks are designed such that connections to the system are on the suction side of the pump aiding the NPSHR which allows for efficient and smooth pump operation. Depending on the application, these tanks can be ASME or Non-ASME code vessels. HEAT can properly design, size, and manufacture expansion tanks or vessels based on specific system design requirements.
When a system is operated at elevated temperatures or when the expansion tank is not the highest point in a system, it is almost always necessary to have an inert blanketing system. The presence of an inert blanketing system on the expansion tank can not only improve the life of a thermal fluid but also of the heat transfer equipment itself. Blanketing systems can significantly reduce the rates of thermal fluid oxidation and can provide improved process performance through improved fluid condition. HEAT, Inc can design and manufacture self-regulating inert blanketing systems for both new and existing equipment.
Fill & Drain Systems can provide a cost-efficient means of fluid management during start-up, shutdown, and maintenance activities. Typically located at the lowest point of the overall process, these systems make it easy to drain and refill large volumes of thermal fluid without the hassle of logistics coordination. HEAT, Inc has the knowledge and experience to design and manufacture Fill & Drain Systems for any size system or process.
Sometimes referred to as “Catch Pots,” Vent and Blow Down Systems are necessary when relief valves or other blow down equipment are not permitted to be channeled into an open container or drain. When thermal fluid is required to be contained at all times, Vent & Blow Down Systems can provide a cost-effective solution for managing unexpected fluid discharges. Vent & Blow Down Systems can also help to avoid regulatory or health concerns related to the discharge of high temperature thermal fluids. HEAT, Inc can design and manufacture Vent & Blow Down Systems for any sized process or condition.
Improperly designed fluid distribution manifolds can undermine the effectiveness of a heat transfer system or process by providing inadequate flow through critical portions of the process equipment. Inadequate flow caused by the manifold design or operation can significantly affect the overall process performance and quality, leading to potentially reduced yields and overall throughput. HEAT, Inc has the technical expertise to design and manufacture manifold distribution systems that will ensure adequate flow through the process equipment, improving the quality and overall efficiency.
Thermal insulation is an important consideration when designing, maintaining, or operating thermal fluid heat transfer systems. The type and operating conditions of a heat transfer system will help to determine the appropriate insulation system to be used (cellular glass, mineral fiber, calcium silicate, etc). If the incorrect insulation is used, serious safety and fire hazards can occur. HEAT can help to inspect, retrofit, or replace any insulation system for not only improving overall thermal efficiency, but also reducing safely hazards associated with improper insulation.
As a heat transfer system ages, maintenance and repair activities will eventually need to be performed on the major components to keep the system running safely and efficiently. HEAT offers a wide range of factory based repair and upgrade services for:
- Flanged Heaters
- Expansion Tanks
- Control Centers
HEAT offers a factory inspection and hot functional testing service for existing or used heat transfer equipment. Factory inspection and testing can help to ensure that a used system is up to code and fit for operational service. HEAT’s in-house testing center can perform a wide variety of functional and operational tests for both new and used equipment.
