Low Pressure Heat Transfer Fluid

MultiTherm 503 Low Pressure Heat Transfer Fluid

MultiTherm 503 ® is a high quality nontoxic Low Pressure Heat Transfer Fluid for use in closed loop liquid phase heating and cooling systems form 50°F to 500°F.

MultiTherm 503 ® has been successfully used in a variety of applications. In the processing industry, it has been used for heating and cooling batch reactor systems. In the plastic industry, MultiTherm 503 ® has been used for hot/cold cycling of molded products and to improve the versatility of laminating lines.

MultiTherm 503 ® provides users with nontoxic, low pressure alternative to synthetic chemical based heat/cool fluids.

MultiTherm 503 ® meets the requirements for FDA regulations 21CFR178.3620(b) nonfood articles in contact with food.

REDUCES EQUIPMENT COSTS

Use in Low Pressure Equipment
Fluids that have high vapor pressure can require complete system pressurization to prevent fluid boiling and pump cavitation. Pressure control systems on expansion tanks and pressure rated piping and equipment can add significantly to equipment costs. In addition, electrical classifications and system gasketing requirements are also affected by low flash point fluids. MultiTherm 503® can be used in standard low pressure fluid heating systems. It has low vapor pressure and high flashpoint (320°F). In addition, it is unreactive with water vapor or air at ambient conditions so expansion tanks do not have to be blanketed.

Efficient Heat Transfer
MultiTherm's physical properties (viscosity, density, thermal conductivity and specific heat) result in higher fluid film coefficients than many other fluids. As a result, heat loads can be achieved with lower flow rates, smaller heat exchangers or lower approach temperatures.

LOWER EXPENSE

Reduced Maintenance Costs
MultiTherm 503 ® can help reduce system maintenance costs. It has excellent metal coating properties and lubricity, which reduce wear on moving parts and protects surfaces from corrosion. Chemically inert, it won't aggressively attack gaskets and seals. And since MultiTherm 503 ® operates in low pressure equipment, there are no pressure control or purging systems to maintain.

Minimize Leak Testing
Fluids with high vapor pressure can require extensive leak testing prior to startup to prevent fluid loss during operation. This can add significantly to total maintenance down time. With MultiTherm 503 ®, system pressure is limited to pump circulating pressure so leak testing requirements are significantly reduced.
