01 / What to put in the first email
Six fields that cut the round trips
Model code
Every code maps to a drawing revision.
Fluid
Glycol concentration by volume. Most first messages miss it.
Connection
Size and thread or flange standard.
Annual volume
Annual quantity, so pricing carries a price break.
Destination
Destination country and the incoterm you work on.
Picture or drawing
A photograph saves a round trip; a drawing saves two.
02 / Symptom routing
Report the symptom, and no part number is required
| Question type | Report | Presented as |
|---|---|---|
| Filtration | Loop volume, the current element micron rating, the differential pressure across it, and the last coolant sample result. | psid · µm · µS/cm |
| Leak | What the panel reports, the rooms or runs in scope, the loop length and the glycol percentage. Say whether the space has downflow air units: 1.8 m of clearance from the discharge prevents most nuisance alarms. | µA · m · % |
| Thermal | The gap, the assembly pressure and the target impedance, rather than a W/m·K figure on its own. | mm · °C·cm²/W |
A symptom message with no part number works.
03 / Response and quotation
What the reply commits to
A first reply arrives inside one working day. Where a figure needs a test record or a check at the manufacturing end, the reply says which record is being pulled and when it will arrive.
A quotation holds for 30 days and names the incoterm, the currency, the model codes with their drawing revisions, the MOQ and the lead time.
| First reply | 1 working day |
| Sent after 18:00 Friday, UTC+8 | answered Monday |
| Quotation validity | 30 days |
| Quotation fields fixed at issue | 6 |
04 / What lands in the inbox
Four worked examples, and the document set behind any code
Ask for the sheet-

Dimensional drawing with its revision · datasheet link per code · burst ratio · MOQ and lead time
Attachments or open PDF links. Nothing sits behind a form. A sample request carries its lead time and test record.
05 / Out of scope
What this address cannot do
An enquiry that cannot be served gets one reply saying so.
Not done on site
Commissioning, flushing and leak repair are not services. The fill and flush line supplies the equipment; the operator runs it.
Not a design authority
Design authority for the loop stays with the buyer's engineer.
Offered instead
A check of the schedule for bore, thread and material conflicts across the product lines.
06 / One message
Email, code, fluid, quantity
Four lines are enough to start. What comes back is the specification sheet, the drawing and the datasheet for the code.
