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.
