Freon Keeper
Refrigerant Leakage Detection System

フロンキーパー外観

What is Freon Keeper?

It is a refrigerant leakage detection system which can be installed to regrigeration units to detect its regrigerant leakage at early stage. Our self-developed system "Freon Keeper" detects refrigerant leakage at 10% by using ultrasonic.

Benefit on an earlier detection of refrigerant leakage

01

Reduction of
leakage amount

Your company can contribute to the prevention of global warming.

02

Cost saving

Avoid increase electricity and repair cost by avoiding continuous operation of refrigeration equipment to shortage in refrigerants.

03

Stable operation of equipment

Enable to prevent a loss of product stocks and sales opportunities and to extend the equipment lifetime by detecting leakage before mal-functioning of refrigeration system.

Characteristic of Freon Keeper

  • 超音波でフロン漏えいを早期発見
  • 冷凍設備をフロンキーパーによってIoT化
  • 電気代・修理費コスト削減

point1
Early detection of refrigerant leakage by ultrasonic detection system

When refrigerant starts leaking, liquid refrigerant which is circulating in the refrigeration units produce flash gas. Ultrasonic detection system can immediately detect this flash gas and enable you to notice regrigerant leakage at early stage before having the temprature sign.

Lack of refrigerant decreases refrigerating efficiency and increases power consumption. Freon Keeper is the only solution to this risk.

performance
Small leakage

One tiny bubble that difficult to perceive by human eyes appears in the sight glass. Freon Keeper can detect the leakage as early as at this stage.

→
Abnormal refrigeration
performance
Large leakage

Large amount of leakage and the increased number of bubbles appear in the sight glass. this left photo shows about 50% of leakage.


point2
IoT transformation for refrigeration equipment

Our unique system detects refrigerent leakage by collecting various data, such as refrigerant pressure and temperature, electric current and ambient temperature, and automatically send them to the server every 10 minutes. This provides a centralized and real-time management system of the regrigeration equipment in various stores using PCs 24 hours/365days.

point3
Saving electricity and repair cost

According to ''Ministry of Economy, Trade and Industry of Japan'', in Japan, yearly 16 % of refrigerant is leaked from seperate show cases which are mostly installed in supermarkets.
According to ''Japan Refrigeration and Air Conditioning Industry Association'' exectlicity consumption increase 40 % by keep operating the refrigeration units with refrigerant leakage of 30 % which cause trmprature trouble of refrigeration units. Detection of 10% refrigerant leakage at early stage can save electricity cost.

Saving electricity cost


Detection of 10% refrigerant leakage at early stage can save electricity cost of:

¥727,700/Year

【Electricity cost in case of 16 % refrigerant leakage in a year.】

133.125kW (10 supermarkets with average) × 1.1 (10% growth of power consumption) × 0.65

(operation load) × 24 hours × 16 yen (1kW/h) = 36,550.8 yen/day

36,550.8 yen × 365 days = 13,341,042 yen/year

13,341,042 - 12,613,342 = ¥727,700

※Average per store [Using date of 10 supermarkets in Tohoku region with average 7.4 refrigeration units/store]

Saving repair cost


Detection of 10% refrigerant leakage at early stage can save repair cost of:

¥159,500/Year

【 Top up cost in case of 16 % refrigerant leakage in a year】

Leakage amount 75kg: 75kg × 4,500 yen (R-404A price/kg) = 337,500 yen
Top up service fee: 75kg × 500 yen = 37,500 yen
Leakage inspetion and repair fee: 3 man-hour × 8hours × 35,000 yen = 105,000 yen
Adjustment fee: 4 times × 50,000 yen = 200,000 yen
Sundry expenses: 68,000 yen
Total: 337,500 + 37,500 + 105,000 + 200,000 + 68,000 = 748,000 yen/year

【Top up cost in case of 10 % refrigerant leakage in a year】

Leakage amount 46kg: 46kg× 4,500 yen (R-404A price/kg) = 207,000 yen
Top up service fee: 46kg × 500 yen = 23,000 yen
Leakage inspetion and repair fee: 3 man-hour × 8hours × 35,000 yen = 105,000 yen
Adjustment fee: 4 times × 50,000 yen = 200,000 yen
Sundry expenses: 53,500 yen
Total: 207,000 + 23,000 + 105,000 + 200,000 + 53,500 = 588,500 yen/year

748,000 - 588,500 = ¥159,500

※Average per store [Using date of 10 supermarkets in Tohoku region with average 7.4 refrigeration units/store]
