BMS equipment: sensors, controllers, valves

A building management system and energy-monitoring loop only run if every measured and controlled point matches the signal type. HTECH supplies field devices and panel hardware — sensors, controllers, valves, expansion modules, energy meters, panel accessories — against the consultant’s or contractor’s point list.

What we supply

• Temperature, humidity, CO2, duct pressure, filter differential, occupancy
• Duct and pipe sensors; dry contacts from motor-control boards
• DDC controllers and analog / digital expansion modules
• Control valves and actuators — two-way or three-way as the HVAC file states
• Energy meters and BACnet or Modbus gateways when specified
• Panel accessories: 24 V supplies, interposing relays, terminals, labels, surge protection

Brands we see often: Tridium, Johnson Controls, Siemens, Honeywell, Global Control 5, Veris, Neptronics. Models follow the drawings. We do not sell a generic “BMS set” before the point count is known.

How to order

1. Send the point list or the equipment sheet: analog in, analog out, digital in, digital out; 0–10 V, 4–20 mA, NTC, dry contact.
2. HTECH proposes an equivalent if the specified model will miss the delivery date.
3. The quotation splits devices, modules and panel accessories.
4. Delivery includes origin and quality documents and the maker’s wiring notes.
5. We support point-to-point checks if the contract includes that line.

Point scope on an equipment order

A building-controls package usually covers HVAC, power and pumps. A wider package adds door contacts, rack cabinets, leak points and signals into a central software. Software licences and programming labour are not inside a materials quote unless written separately.

Questions we hear first

Can we buy a few sensors only?

Yes. State the range, output type, 24 V or 230 V supply, duct or wall mount.

Can you match one-for-one on a live system?

We need a photo of the label, the termination drawing and the input type on the controller. Do not buy “the same shape” if the signal differs.
