At PMJ Heaters Manufacturing, we pride ourselves on being a trusted Malaysian-based manufacturer specializing in the design and production of customized industrial heaters and thermocouples. Strategically located in Johor Bahru, we serve diverse industries such as food processing, offshore marine, and the medical sector with durable, high-performance heating solutions tailored to meet specific application needs.
Precision-Engineered Industrial Heaters for Demanding Applications
Our range of industrial heaters is meticulously engineered for precision, efficiency, and long-term reliability. Whether it’s a compact cartridge heater or a rugged immersion heater, we leverage cutting-edge manufacturing processes to ensure superior heat transfer, energy efficiency, and operational consistency.
Types of Heaters We Offer
-
Cartridge Heaters: Built for localized heating, our cartridge heaters deliver concentrated heat exactly where it’s needed. Widely used in mold & die applications, these units are known for rapid heat-up times and excellent thermal conductivity.
-
Immersion Heaters: Ideal for heating liquids such as water, oils, and chemicals in tanks and reservoirs. Our immersion heaters are crafted using high-grade stainless steel and Incoloy, ensuring corrosion resistance and prolonged life, especially in marine and offshore environments.
-
Band Heaters: Designed to fit snugly around barrels or cylindrical components. These are essential for plastic processing, extrusion, and injection molding applications.
-
Tubular Heaters: Versatile and customizable in shape, these heaters are perfect for air, gas, and surface heating across multiple industries.
Customized Thermocouples – Unmatched Accuracy in Temperature Measurement
Thermocouples are critical in maintaining process integrity in high-stakes industries. At PMJ Heaters Manufacturing, we develop custom thermocouples with precision materials and configurations, ensuring accurate temperature sensing in extreme conditions.
Thermocouple Features
-
Multiple junction types (K, J, T, E, N, R, S, and B)
-
Mineral-insulated for rugged performance
-
Custom sheath materials such as stainless steel, Inconel, and ceramic
-
High-temperature compatibility up to 1800°C
-
Intrinsically safe designs for hazardous environments
Our thermocouples are a vital component in food-grade equipment, sterilization chambers, marine engine monitoring systems, and medical device calibration.
Supporting the Food Processing Industry with Reliable Heating Systems
In the food processing industry, consistency, hygiene, and precision are non-negotiable. Our heaters are extensively used in ovens, fryers, packaging equipment, pasteurizers, and sterilization tanks. We design every unit to meet food safety standards and provide even, controllable heating to reduce waste and improve product quality.
-
Stainless steel sheathed heaters ensure food-safe contact
-
Moisture-resistant insulation prevents performance degradation
-
Custom wattage density prevents overheating and maintains energy efficiency
Our robust heaters contribute to faster cooking times, precise thermal control, and enhanced process reliability, giving food manufacturers a competitive edge.
Offshore and Marine-Grade Heaters – Built for Harsh Environments
Offshore operations demand equipment that can withstand saltwater corrosion, high pressure, and extreme temperatures. PMJ Heaters supplies marine-certified heaters and sensor systems for:
-
Crude oil separation
-
Chemical injection systems
-
Diesel engine preheating
-
Ballast water treatment
-
Subsea valve and actuator heating
Each marine heater is designed with IP-rated enclosures, ATEX compliance, and robust marine-grade alloys to offer longevity in corrosive offshore environments.
Advanced Medical-Grade Heating for Critical Applications
The medical industry requires absolute temperature control to safeguard both patient safety and equipment functionality. PMJ Heaters delivers sterile, low-leakage heating elements used in:
-
Autoclaves and sterilizers
-
Medical incubators
-
MRI and imaging systems
-
Blood analyzers and IV warmers
Every product is manufactured in cleanroom environments, utilizing biocompatible materials and adhering to ISO 13485 standards. Our engineers work closely with medical OEMs to ensure compliance with international regulatory requirements.
