How to Send a Clear RFQ for Custom Heating Elements
A clear RFQ helps us check specifications faster, reduce wrong quotations and match the right supplier. This guide shows what details to send for tubular heaters, immersion heaters, cartridge heaters, band heaters, thermocouples and heating-related parts.
Fastest way to start
If you do not know all specifications, send us the product photo first. We will help check what is missing.
Details to send for faster quotation
You do not need to prepare a perfect technical document. But the more key information you send, the faster we can check and quote.
Different heaters need different key parameters
Custom heating products are not all the same. Below are the common details we need for each product type.
| Product Type | Key Details to Send | Helpful Notes |
|---|---|---|
| Tubular Heater | Voltage, wattage, tube diameter, tube length, total length, material, shape, lead wire, quantity | Photos or drawings are very helpful, especially for bent shapes or special mounting structures. |
| Immersion Heater | Voltage, wattage, flange/thread size, tube material, heating length, liquid type, tank condition | Please tell us whether it is used for water, oil, chemical liquid or other medium. |
| Cartridge Heater | Diameter, length, voltage, wattage, lead wire type, right angle or straight lead, working temperature | For mold heating, fit tolerance and lead wire direction can be important. |
| Band Heater | Inner diameter, width, voltage, wattage, material type, terminal position, thermocouple hole if needed | Please send machine or old heater photos if you are not sure about the terminal structure. |
| Finned Air Heater | Voltage, wattage, tube size, fin size, total length, mounting type, air duct or oven condition | Tell us air heating application and approximate working temperature. |
| Thermocouple / Sensor | Type K/J/PT100, probe diameter, probe length, cable length, connector type, working temperature | Old sample photo and connector photo can reduce mismatch risk. |
| Heating Accessories | Product name, photo, model, quantity, voltage/current requirement if applicable | Can be sourced together with heater orders to save communication time. |
Copy this message and send it to us
This is a simple RFQ format. You can send it by WhatsApp or email. Attach product photos or drawings if available.
What usually delays quotation?
Most delays come from missing parameters or unclear application conditions. These are the most common issues we help buyers clarify.
Custom heaters need voltage, wattage, size, material and quantity. A photo alone may not be enough.
Tube diameter, heating length, total length, flange size or thread size can affect price and production.
Heating water, oil, air, mold or chemical liquid may require different materials and structures.
Sample price and bulk price can be different. Please tell us sample quantity and future order plan.
Shipping cost and packing method depend on the destination country and total weight.
Many industrial heaters are custom-made, so old samples or drawings are very useful.
