Reduction of electrical energy consumption of refrigeration system

Adoption of refrigeration process to variable production capacity

Variable production costs reduction

Extended life span of refrigeration equipment

24/7 KPI tracking

Dween is a chief engineer who doesn’t manage people. It orchestrates and optimizes your technological processes.

DWEEN Cold continuously monitors the temperature parameters of all refrigeration consumers across the facility and dynamically adjusts refrigeration equipment settings to ensure that the required technological temperature conditions are consistently maintained.

Electrical energy consumption is reduced through continuous monitoring of system performance and advanced control of evaporation temperature and pressure parameters, adjusted in real time according to actual refrigeration demand and current production volumes.

Weekly technological-compliance band for seventeen controlled-temperature rooms and freezing tunnels. Almost all intervals are in specification; one finished-product cold store shows a sustained out-of-specification period mid-week.

DWEEN Cold control panel — technological compliance per consumer.

In just 1 minute, Dween assesses and computes all of your equipment parameters 4 times.

No new field equipment, no changes to your machinery. Existing SCADA, PLC and metering data is utilized.

About us
01

Read

Data of every refrigeration system component is gathered every 15 seconds and stored in DWEEN Cloud.

02

Calculate

DWEEN Cold estimates the real-time refrigeration demand.

03

Adjust

Essential setting changes are written back to the control system.

04

Check

Every consumer is evaluated against its temperature limits, alerting on technological non-compliance.

Everything is under control

DWEEN Cold is responsible for full scope monitoring and control. The exact list is fixed in your proposal before anything is signed.

How DWEEN Cold works?
It’s easy.

A cloud-based system has unlimited resources to store and evaluate important data. A conventional PLC is limited.

1

We add an advanced layer of digital power to your existing hardware.

2

Real-time operation data is being collected.

3

DWEEN Cold runs the refrigeration system autonomously.
