At Q-TECH, we apply the same clear rules for everyone: the law protects you, and when applied correctly, it protects us as well. By processing your purchase, you accept our General Terms and Conditions of Sale. If you are purchasing as a consumer (B2C), nothing stated herein limits the rights granted to you by mandatory law (RDL 1/2007, TRLGDCU): the 3-year legal warranty of conformity and the right of withdrawal under the terms and with the exceptions legally provided, which are detailed below. References to "B2B" apply only to businesses and professionals.

Your guarantees

  • Rights intact: 14 days of withdrawal from receipt for most products—subject to the legal exceptions you will see below, such as goods made to your specifications—and a 3-year legal warranty of conformity, under the terms of the TRLGDCU.
  • Conformity with the description: we guarantee that the equipment will correspond to the published technical description and what one could reasonably expect from it (arts. 115 et seq. TRLGDCU). Images and videos are for guidance only: the manufacturer may supply a more recent revision of the product or introduce minor aesthetic, packaging, or firmware changes, without this constituting a lack of conformity as long as the described characteristics and performance are maintained.
  • Traceability that also protects you: we document the condition, serial number, and seal of each piece of equipment upon shipment, and we video-record the opening of returns; this is your proof of the condition in which the goods were delivered.

Responsible use and your part

  • If you are thinking of returning it, keep it as you received it: without installing or activating it, with its seals, accessories, and packaging intact. This is how to ensure a full refund, without deductions.
  • Handling that exceeds inspection reduces value: handling the equipment beyond what is necessary to verify its nature and operation may result in a real, assessed, and case-by-case justified deduction (art. 108.2 TRLGDCU), never a fixed percentage. In particular: activating or registering the serial number, linking it to a manufacturer's account or app, circulating water through hydraulic equipment, unsealing probes, or installing software or consumables. Initial inspection of the product does not lead to a deduction.
  • The same item must be returned: withdrawal requires returning the supplied unit. Different equipment, or equipment with prior use, age, or wear prior to purchase, does not constitute a valid withdrawal.
  • Installation and cybersecurity, shared responsibility: this is technical hardware; you are responsible for correct installation, credentials, patches, and backups, while we deliver a compliant product. Q-TECH is not liable for damages resulting from poor installation, incorrect configuration, or omission of patches by the customer or third parties (in B2C, without prejudice to the legal warranty and liability for intent or negligence, arts. 86 and 130 TRLGDCU).
  • Delivery of bulky goods: delivery is made to the curb. B2C: transport risk is ours until physical delivery (art. 66 ter); we recommend noting visible damages on the delivery note and notifying us of breakages within 24-48 hours with photographs to activate the insurance. B2B: inspection and notation on the delivery note are mandatory; hidden damages must be reported within 24 hours (art. 366 CCom). Unjustified rejection or incorrect shipping information will entail the actual outbound and return costs (approx. €85-550 for heavy machinery).

Made to your measure (Advanced Pre-Assembly)

  • If your order includes equipment, racks, hydraulic assemblies, or technical rooms made or configured according to your specifications (permanent joints, custom cuts or wiring, parameterization, pressure testing), these are custom goods without the right of withdrawal from the conclusion of the contract (art. 103.c TRLGDCU; CJEU Case C-529/19), which is informed before purchasing and documented in the signed Order Note. A test you request without permanent modification retains your right of withdrawal, with only the actual loss of value caused by that test being deducted. Would you prefer to receive it tested, configured, and ready to connect, without assuming these risks? Contract our Advanced Pre-Assembly or the prior technical audit.

If you are purchasing as a business or professional (B2B)

  • The transaction is governed by the Commercial Code: firm sale, without the right of withdrawal; notification of defects within 4 days (apparent) / 30 days (hidden), arts. 336 and 342. Q-TECH acts as a distributor and excludes indirect damages, loss of profit, and data loss, limited to the price of the equipment, without prejudice to the manufacturer's commercial warranty.

ESBE CRA120 controller: constant flow temperature with a 15 Nm actuator for large valves

The ESBE CRA120 controller combines a 15 Nm actuator and a constant temperature controller for large rotary mixing valves, such as the ESBE 3F. It keeps a constant flow between 5 and 95 °C with a wall-mounted control box and display. In a Q-Tech pre-assembled plant room it arrives fitted to its valve, set and tested.

What is the ESBE CRA120?

The ESBE CRA120 is a constant temperature controller for large rotary mixing valves that turns the valve with a 15 Nm actuator to hold the setpoint. It measures the water with its pipe sensor and is set with push buttons on a wall-mounted control box. The actuator can be operated by hand with a release button and a lever.

What problem does it solve?

Flanged valves in large installations, such as the ESBE 3F, need more torque than a threaded domestic valve. ESBE does not specify its 6 Nm controllers for these valves and recommends the CRA120 for the F series.

The CRA120 provides the torque these valves need and places the setting display on the wall, away from the valve. So the installer can adjust the setpoint even when the actuator sits in a hard-to-reach position.

Compatibility and limits

  • ESBE recommends it for the F series up to DN100: the ESBE 3F from DN40 to DN100 and the whole ESBE 4F range.
  • For the 3F in DN125 and DN150, ESBE offers the 30 Nm ARC300 actuator, which needs a separate controller.
  • It includes the 900 adaptor kit for the F, MG, G, BIV, T and H series. For VRG, VRB and VRH valves, order the VRG801 kit separately.
  • ESBE offers kits for Honeywell, Siemens, Meibes, Watts, TA, Schneider Electric and Viessmann valves, sold separately.
  • The sensor must be insulated from the ambient temperature. The 5 m CRA911 sensor helps when the 1.5 m sensor does not reach.

When this product is not the right choice

  • For threaded VRG domestic valves, the 6 Nm ESBE CRA211 controller, with the controller built into the actuator, is enough.
  • If your system already has a controller, an actuator is enough: the 15 Nm series 90.
  • If the temperature should follow the outdoor temperature, look for a weather-compensating controller from the CRC120 series.

Frequently asked questions

Which model do I need?

The CRA121 if you have 230 V in the plant room; the CRA122 if your panel works at 24 V. Both have the same torque and range.

Does it fit the ESBE 3F?

Yes, up to DN100, according to ESBE's recommendation. It mounts with the included 900 kit.

Where does the display go?

On a wall-mounted control box, connected to the actuator with a 1.5 m cable. So it can be set even when the valve is high up.

What is the delivery time?

We keep it in stock at our warehouse; if it sold out, we would order it urgently and confirm the lead time.

Q-Tech installation and support

Q-Tech fits the CRA120 to its valve, mounts the control box and checks the control inside the pre-assembled plant room, through workshop pre-assembly. So the large circuit arrives controlled and tested on site. If your plant room is already installed, the on-site hourly Expert Technician fits and configures the controller. For help choosing, book a technical call or contact us on WhatsApp. More models in valves and accessories.
