Precision Temperature Control in Life-Saving Environments

Medical devices depend on precise, reliable heat. Whether it’s warming fluids, heating gases, sterilizing equipment, or maintaining stable temperatures in lab environments, even small swings in temperature can affect patient outcomes and device performance.

Backer Hotwatt has nearly 70 years of experience designing and manufacturing heaters for medical OEMs, and Selmark supports medical engineering teams across New England who rely on these solutions to meet strict performance and regulatory requirements.

Tight Temperature
Control

Backer Hotwatt heaters are built to maintain stable, repeatable temperatures—even in devices that have very small thermal margins.

• Supports procedures where a drift of only a few degrees can affect outcomes, such as fluid warming, insufflation, and ablation.

• Delivers reliable performance for long run times, including in sterilization and incubation systems that must hold temperature for hours at a time.

• Helps meet strict regulatory and quality requirements for consistency in patient-facing and lab applications.

Long Life & Consistent Performance

Medical devices often run continuously or cycle thousands of times, so heater reliability matters. Backer Hotwatt designs for long life, predictable output, and stable heating profiles.

• Reduces device downtime and maintenance needs, which is especially important in surgical and diagnostic settings.

• Ensures stable performance across repeated heating cycles, a key requirement for sterilization, fluid pumps, and lab equipment.

• Helps avoid early failure modes because the heaters are constructed for durability and tested under strict quality controls.

Typical heater type: Air process heater

Insufflation devices warm gases—often CO₂—to improve patient comfort and help clinicians work more efficiently. These systems need a heater that responds quickly and holds temperature steady as gas flow changes. Backer Hotwatt’s air process heaters deliver consistent, repeatable heat for these small, fast-moving air paths.

Used in:

• Laparoscopic insufflators

• GI procedure systems

Air Heater for Sterilization Systems.

Typical heater type: Fluid Immersion Heater

Ablation systems heat saline to a target temperature—around 90°C—and must stay within a narrow range during the entire treatment. Backer Hotwatt’s compact immersion and fluid heaters provide even heating for these closed fluid paths, helping clinicians maintain controlled, predictable output.

Used in:

• Saline-based ablation devices

Typical heater type: Air Process Heater

Cell incubation systems need steady, uniform heat to support cell growth, maintain sterility, and provide clean thermal cycles for repeated use. Hotwatt’s air heaters offer the stable, long-duration output these systems require.

Used in:

• Cell culture incubators

• Laboratory growth and disinfection systems
