Planning collective laundry room management

This article describes the installation planning. For on-site implementation and setup of equipment on the Climkit platform, please refer to the links at the end of the article.

1. Collective Laundry Management

Climkit offers a turnkey solution combining an RFID reader and relay meters managed by the Climkit Gateway to control and measure the use of washing machines, tumble dryers, and "secomats" (vending machines for laundry supplies).

Operation:

  1. The user identifies themselves with their badge and enters the desired machine number on the keypad.
  2. If the badge is valid, the corresponding relay is activated, powering the machine. A transaction is created, and the meter takes an initial reading.
  3. To finish, the user badges in again and enters the machine number. The meter takes a second reading, and the consumed energy is recorded in their account.
  4. Via the online platform, Climkit directly bills users for consumption at a per-kWh rate that accounts for electricity costs as well as machine maintenance and depreciation fees.

Wiring Diagrams

Option with a single washing column

When there is only one machine or one washing column (washing machine + tumble dryer), a simple badge reader can be installed.

RFID Badge Reader

RFID readers are useful for identifying laundry consumers to ensure fair billing. Each consumer holds a personal and non-transferable RFID badge.

The badge contains a unique token read by the RFID reader or terminal. If the token is registered in the platform and is in the Accepted status, the transaction (washing or charging) is authorized.

Relay Meter

Relay meters are devices that function as both an energy meter and a switch to activate or deactivate a load.

Cold Water Meter

It is also possible to read the cold water meter supplying the washing machine to bill the corresponding water consumption.

Climkit Offer

The standard Climkit offer groups the necessary elements for system operation: hardware, software functionalities, as well as services related to implementation.

All hardware is supplied preconfigured to simplify installation and ensure correct meter communication.

  • Equipment:
    • LAN router or 4G router
    • Climkit Gateway
    • PoE Switch
    • RFID reader with or without keypad
    • Three-phase relay meter
  • Software functionalities:
    • Management of RFID readers and relay meters for laundries
  • Implementation services:
    • Technical coordination and verification of meter readings
    • Administrative commissioning

All products are ordered directly from Climkit.

In most cases, the installation can be performed by the installer without on-site intervention from a Climkit technician.

Telephone support is available if necessary during commissioning.

Equipment Details

4G Router

An Internet connection is essential for the system to function. If no connection is available, Climkit can provide one via a 4G router equipped with an active multi-operator SIM card.

Using the Climkit TRB140 4G router presents several advantages:

  • Simplified installation: the router easily installs inside the electrical cabinet, directly on the DIN rail
  • Complete delivery: supplied with its DIN rail mount and 24V DC power supply
  • Ready to use: delivered preconfigured with an activated SIM card
  • Economical 4G subscription: low-cost internet connection

Climkit Gateway

Acting as a gateway between the solution and the web platform, the Gateway uses its RS485 port to connect directly to the relay meters and RFID readers.

PoE Switch

When multiple devices need to be connected via Ethernet, a switch is required.

Model supplied: Teltonika TSW200 (or equivalent) - 8 PoE Ethernet ports.

PoE ports directly power Wi-Fi access points and RFID readers with electricity.

The switch is delivered with a DIN rail mount and its 48V DC 150W power supply.

RFID Badge Reader

The RFID reader connects to the same computer network as the Gateway via Ethernet and is powered by PoE (through the same Ethernet cable).

The model with a keypad is used by default for collective laundry management:

The simple reader without a numeric keypad is used to activate a single load, such as a washing column in a laundry room (washing machine and tumble dryer).

Direct Relay Meter >80A

The model used for collective laundry management is the Eastron SDM530C.

It is a three-phase relay meter (max 100A) connected via RS485 Modbus to the Gateway.
