Pharmaceutical Machinery
Blister and tube sealing, granulation drying, jacketed vessels and validated temperature measurement.
Repeatability is the specification. A process that drifts is a batch that fails.
The process, and where the heat goes in
Read left to right. Each block is a place on the machine that has to be held at a temperature, coloured by how hot it runs.

Zone by zone
This table is the whole argument for the page. It maps the machine you already have to the element type that suits each position on it, and every product name links to the family page with the sizes, the options and the codes.
| Zone | Duty | Typical temperature | Swiftheat product | Why this element |
|---|---|---|---|---|
| Fluid bed and granulation dryers | Air heating, continuous | 40 to 120 °C | Tubular Heaters | Finned elements into a clean, high flow air stream |
| Blister forming station | Cyclic, flat tool | 110 to 160 °C | Cartridge Heaters | Bore mounted in the forming plate, even across the web |
| Blister sealing station | Cyclic, flat tool | 150 to 220 °C | Cartridge Heaters | Distributed wattage so every cavity seals the same |
| Tube and sachet sealing | Cyclic, small tools | 140 to 220 °C | Cartridge Heaters | Small diameter cartridges, protected leads on a moving jaw |
| Jacketed vessels | Immersed or clamped | 40 to 150 °C | Tubular Heaters | Sheath chosen for the jacket medium |
| Control loop | Measurement | - | Thermocouples and Temperature Sensors | PT100 where stability and repeatability matter more than speed |
Temperatures are typical for the process and are given as a starting point. Send us the zone temperatures your machine actually runs at and we will work back to a safe loading.
Products for pharmaceutical machinery
A shortlist, not the whole catalogue.
-
Cartridge Heaters
Bore mounted in moulds, platens and dies. Round, swaged, made to your length.
-
Tubular Heaters
Air, liquids and surfaces. Straight, U form, W form or coiled to your drawing.
-
Thermocouples and Temperature Sensors
Types J, K, N, T, E, R, S, B and C, plus PT100, PT500 and PT1000 RTDs, made to length.
-
Strip Heaters
Flat and gently curved surfaces, sealing bars, platens and duct air.
-
Ceramic Infrared Heaters
Radiant surface heating, thermoforming, drying and preheating.
Application notes
PT100 where the record matters
A platinum RTD drifts less than a thermocouple and repeats better between sensors. On a process that has to produce the same record batch after batch, that stability is the reason to choose it, even though it is slower.
Even sealing across every cavity
A sealing plate that is two degrees cooler at one corner produces a blister that fails leak testing in exactly that corner. Distributed wattage and a measured hole pattern are how that is fixed at the heater rather than at the controller.
Clean air means clean elements
In a granulation dryer the element sits in the air path that reaches the product. Finish, sheath material and the absence of anything that can shed matter as much as the wattage.
What to send us
An enquiry with these in it can be quoted the same day. An enquiry without them takes three phone calls first.
- Machine type: blister, tube filling, granulation, coating or filling
- Tool or plate dimensions and the existing bore pattern
- Operating temperature and the tolerance the process is validated to
- Cycles per hour
- Sensor type the controller expects, and whether PT100 is required
- Any material or documentation requirement that affects sheath choice
A photograph of the old element next to a tape measure is worth more than a paragraph of description, and a drawing is worth more than both.
Build the list instead
If you are replacing several elements at once, the list builder walks through each one, draws it as you specify it, and produces a single printable document you can send by email or on WhatsApp.
