Mini Clean Flow - Stream Heater

Mini Clean Flow Heater

A biotechnology company approached BCE in need of a custom heating solution. Their application required that the media must be heated to 75 °C in order to eliminate any pathogenic bacteria that may be present. Their current system was not heating the medium efficiently requiring a high watt density solution causing heater failure and carbonization of the material.

SCOPE

The Mini Clean Flow - Stream heater needed to satisfy the following:

• Outlet of temperature of 75 °C (± 2 °C) to eliminate bacteria
• Ability to place heater in a series flow configuration if necessary
• Built in thermocouple for accurate temperature measurement
• 185 Watt, 120 Volt
• All wetted surfaces must be 304 Stainless Steel
• Watt density below 30 WSI to avoid damage to the fluid or system

OUTCOME

BCE designed a double wall inline heater with exceptional heat uniformity and reduced heat losses. The Mini Clean Flow Stream heater was built with internal components designed to turbulate the medium to increase efficiency and minimize watt density. This compact, low mass heater had the ability to precisely control the inner temperature for either over-temp or process medium control. The Mini Clean Flow – Stream was the ultimate solution for this application resulting in a more efficient process to eliminate pathogenic material.

Save Time and Money in the Long Run: Choose a Custom Electric Heater When It Comes to Heating Clean and Ultra-pure Fluids

Custom heater for clean and ultra-pure fluids (from BCE)

What do the fuel cell, bio-med, laboratory, food, pharmaceutical, medical, semiconductor, and electronics industries all have in common? Applications in their processes requiring a fast responding and accurate high purity fluid heater.

Each of these industries include manufacturing processes that require a small and efficient heating source as a component of their production. These heaters must be ruggedly designed, made from materials immune to process contamination, and be vacuum tight. The heaters will be subject to high temperatures, harsh solvents, and corrosive gases. Many times they must maintain a seal for full vacuum, demonstrate a unique heating profile, and maintain very close control.

Common requirements in these processes:

• Capable of handling high vacuum.
• High temperatures.
• Isolation the process media from heating element.
• Isolation from other area of contamination.
• Very accurate control, including internal sensors.
• Fast heat up and cool down.

Few manufacturers offer electric heaters with all of these features with an off-the-shelf product, so a custom (or semi-custom) heater is required. Heater customization allows for specific application requirement to be addressed. Examples are type of internal sensor (RTD or TC), the use of chemical inert glass liners, a profiled heating pattern, and specific wetted materials.

Using stock screw plug immersion heater for these applications should be avoided. This category of heater will not stand up to the rigors of the application, as they are designed for general industrial service. They are not intended for high purity, will not meet material compatibility requirements, have poor controllability and are bulky in size.

The answer is in a custom high purity fluid heater designed with the specific process in mind.

Benefits of developing a custom fluid heaters are:

• Available in a variety of voltages.
• Available in a wide range of watt densities.
• Temperatures up to 350°C.
• Effective heated area can be profiled to generate a liner temperature profile.
• Vacuum compatible up to 1.0 x 10-8  STD. CC/SEC Helium.
• Can be provided with internal sensors (RTD or thermocouples).
• Can be glass lined for ultra pure gas application.

Careful review of the application is important and the help of an experienced heater application engineer is required. Choose a vendor with a long, proven track record of success. The outcome of the test, process or product will be infinitely improved.

Electric In-line Clean Fluid Heater Provides On-demand Heat in a Small Package

Clean fluid, flow-through heating system.

Many original equipment manufacturers require precise temperature control and a very compact package to heat clean fluids. Equipment examples are semiconductor gas processing equipment, kidney dialysis (hemodialysis) machines, process gas analyzers, ink preheating systems, photoresist coating equipment, and parts cleaning equipment.

Electric heaters used in these applications must be compact, lightweight, and made of materials that won't contaminate samples. They also must be fast responding and provide large amounts of power when required.

BCE, a Northern California manufacturer of custom electric heating elements, developed their "Mini Clean Flow" heater for these types of applications. The Mini Clean Flow is a very compact, fast responding electric heating element designed for applications where the heating of clean fluids is required, most often in the semiconductor, medical, and laboratory equipment industries. Designed with high power ratings wrapped in a small package, these specialized heaters offer ultra-fast heat-up and precise, accurate temperature control.

Mini Clean Flow heaters combine inlet and outlet connections along with a baffled stainless steel enclosure, creating a turbulent flow pattern for efficient heat transfer. Sealed resistance heaters are used to isolate process fluids from having contact with the elements directly. Internal thermocouples provide for outlet temperature regulation as well as for maximum sheath temperature control.  The Mini Clean Flow's advanced mechanical design, along with its high power density and overall low mass, provides the end-user with a very efficient and precise heating solution.
