Thermal solutions and temperature sensors for clinical diagnostic instruments

Watlow provides thermal solutions for the development of clinical diagnostic instrumentation. Its equipment ensures uniform operating temperatures and rapid prototyping, including proof-of-concept testing and design iterations.

Watlow’s ASPYRE thyristor power controllers (SCR) family is flexible and scalable, with a variety of options allowing one platform to be re-used across a wide range of applications.
Watlow’s EZ-LINK™ mobile app allows users to set up, monitor and adjust Watlow® EZ-ZONE® controllers via Bluetooth® wireless technology.
The F4T with INTUITION temperature and process controller offers a wide range of field-removable input-output (I/O) modules.
The FLUENT® in-line heater optimises thermal system performance to provide on-demand heating solutions.
The ULTRAMIC® ceramic heaters are designed for thermal applications where a high-performance ceramic heater is required to ensure optimal effectiveness of the equipment and process.
Watlow’s FLUENT in-line heater is a small, lightweight and robust integrated thermal solution.
Watlow designs and manufactures high-quality integrated thermal system components.
The company has three technology centres in the US, Mexico, Europe and Asia.
Smart algorithms enable ASPYRE to easily control a wide range of load types.

Available products include ceramic, in-line, polyimide and silicone rubber heaters, as well as multi-function controllers and sensor technologies.

Watlow’s sensor and wire cable offerings include thermocouples, resistance temperature detectors (RTD) and thermistors, as well as wires, mineral insulated cables and connectors.

Advanced ceramic heaters

Watlow’s ULTRAMIC is an advanced ceramic heater with high-thermal conductivity for a ramp rate of up to 150°C (270°F) per second. This robust system meets global safety standards, including Conformité Européene (CE), Underwriters Laboratories (UL) and Restriction of Hazardous Substances (RoHS) directives.

ULTRAMIC’s electrical performance assures low leakage current, while its type K thermocouple optimises its accuracy and temperature sensing abilities. It also has high electrical isolation and chemical resistance.

Constructed from aluminium nitrade (AIN), the unit is suitable for applications requiring a non-contaminating heat source and geometric stability. It can operate at temperatures up to 400°C (752°F).

In-line heaters for high limit control

Watlow’s FLUENT in-line heater is a small, lightweight and robust integrated thermal solution with high-watt density and an internal thermocouple for high limit control.

The unit replaces multiple components such as traditional immersion-type heaters, integrating a cost-effective design with fast responses and high performance.

FLUENT also features Watlow’s patented spray technology, which optimises heat transfer and temperature uniformity.

Polymide heaters for low-vacuum outgassing

Watlow’s Polymide Heaters comprise a thin, lightweight polymer film that results in thermal stability over a wide temperature range.

This transparent material provides high-tensile strength and tear-resistance, while also allowing medical device users to inspect internal mechanics.

It is also resistant to radiation, chemical interference and fungal spores, as well as being suitable for applications requiring low outgassing in a vacuum.

Silicone rubber heater solutions

Watlow’s customisable silicone rubber heaters supply heat for a large number of situations, including improving heat transfer, quick warm-ups and decreasing wattage requirements.

This lightweight solution is made from fibreglass-enforced silicone rubber that provides dimensional stability without loss of flexibility. Due to its thin design, heat transfer is rapid and efficient. It can also be used for applications where space is limited.

With more than 80 customisable designs, Watlow’s rubber heaters are constructed with wire-wound or etched foil elements, which provide a dynamic approach with repeatable watt-density distribution.

The products are also moisture and chemical-resistant to extend heater service life.

Thermal system controllers for medical devices

The EZ-ZONE PM panel-mount controller offers a simple-to-use interface for the management of current flow in thermal systems. It has a wide range of serial communications capabilities and provides alarm indications if an output device or heater load fails.

The unit can be ordered as a proportional–integral–derivative (PID) controller or combined into an integrated design.

Watlow’s SERIES EHG SL10 is an integrated, multi-function controller that comprises a heater, an adjustable set-point temperature controller, a high / low-temperature alert, a power switching device and a high-temperature safety limit.

It complies with the safety requirements of UL® 1998 and CE 60730.

FIREROD® Cartridge Heaters for Premature Infants

It is critical for premature infants to maintain a constant temperature. Premature babies often have less body fat compared to full-term infants, which can make it difficult for them to regulate their own body temperature.

Efficient Power Control for Electrical Heating Applications

When energy efficiency is important to the process, end-users, machine builders and system integrators need to choose solutions that offer the best performance, ease-of-use and reliability. Whether replacing an existing product or building a new process, the Eurotherm EPack Power Controller range is IoT-ready and has been carefully designed for fast integration and optimum efficiency in industrial systems.

Mini8® Controller

The Mini8® loop controller offers high performance control usually only found in Eurotherm® panel-mount PID controllers.

Unlock the Secrets of Annex 1 Compliance: Free Webinar on the QbD Approach and Quality Risk Management

In a bid to demystify the recent updates to Annex 1 of the European Union GMP Guide, Watlow is hosting a free live webinar on February 28th, 2024, at 4pm CET – 10am EST. Aimed at Quality Assurance, Quality Control, and Plant Operations managers in the pharmaceutical industry, this 60-minute session will unravel the complexities of the revised Annex 1, focusing on the crucial Quality Risk Management process mandated by the Quality-by-Design (QbD) systematic approach.

The Role of Heating Technology in Medical Equipment

There are around 10,000 different medical devices on the market today. Each individual piece of equipment must be manufactured to the highest standards to ensure accurate, efficient and safe results. Here, Andy Selvy, Chief System Designer at industrial technology company Watlow, discusses medical device trends and how heating technology plays a vital role in the function of medical equipment.

Heating Equipment Manufacturer Celebrates 100-Year Anniversary

Industrial heating technology manufacturer Watlow, which specialises in electric components for complete thermal systems, has reached its 100-year anniversary milestone. The company, which was founded in 1922 in Missouri, USA, is now a global electric heating specialist with over 1,000 patents and 4,200 employees working across locations in North America, Asia and Europe.

Case Study: Cartridge Heaters Warming Premature Infants

It is critical for premature infants to maintain a constant temperature. Premature babies normally have little body fat and can struggle to regulate their own temperature. Infants can lose body heat four times faster than adults, and if a baby’s skin temperature drops just one degree, the baby’s oxygen use can increase by 10%.
