Quickly estimate typical and heavy walk-in cooler and freezer refrigeration loads from 6x6 up to 40x40 with an 8 or 10 ft height.
Also includes estimates for motors, lighting, and occupancy loads plus air changes and useful electrical formulas.
User can manually adjust the refrigeration load by adding in values found in the "More Estimates" section.
A useful tool for the refrigeration tradesman.
Refrigeration load is based on a 95* ambient.
Designed by and for the refrigeration service engineer.
Furthermore, this is the only PT app with the ability to use imperial and metric units at the same time. And best of all… it’s free!

Each refrigerant is represented by a “dot” above the pressure wheel. Swipe left or right across the refrigerant bottle to switch to the refrigerant you desire. The color of the refrigerant bottle will match the official code for that refrigerant. The oil type, global warming potential, safety group, and corresponding pressure temperature wheel are also displayed. Swipe the temp –pressure wheel left or right to view the saturated pressure and temperature values.
The units are specified by using the buttons on the sides. If a unit is highlighted green, then the wheel beside it displays values in that unit. Additionally, the font color of the wheel will match the font color of the button selected. Any combination of units can be selected to view, such as Celsius and psig or Fahrenheit and bar at the same time.
Press the arrow on the left or right side to jump to either end of the wheel. The left arrow will move to the lowest temperature available and the right will move to the highest temperature.
Touch the “Refrigerants” menu button to narrow down the list of refrigerants available.
Each refrigerant that has a checkmark will be available to view from the main screen (and represented by a “dot”).
More Information Button:
Additional information can also be found for each refrigerant by touching the "Ref. Info" menu button.
Here information such as molecular mass, critical temperature, critical pressure and other valuable data can be found.
Starting from the data relevant to the working temperature and cooling/heating capacity, the application calculates the valve size suitable for the manufacturer needs.
The algorithm model that makes the calculations has been developed thanks to the CAREL yearly experience in several application fields.
The app is available in both the International Metric System (SI) and the Imperial system.
This free Sabroe app tells you exactly what’s happened if anything goes wrong on a compressor fitted with the Unisab III controller and it gives you a good idea of what might have caused the irregularities.
The app means you and your staff can react promptly if anything isn’t right, limiting downtime and disruption costs.
The app utilizes email as carrier of information from the Unisab’s. On www.sabroe.com you can find information on how to configure your Unisab III controller to send emails to any chosen address if anything happens, and you can find more info on using the app.
Sabroe Factory Denmark is a Johnson Controls business unit that is the world’s leading manufacturer of compressors, chillers and control systems for industrial refrigeration.
In 2012 KRIWAN already began a new era in system protection with the INT69 Diagnose protection unit and its INTelligence software. The new INTspector app 2.0 now makes monitoring, evaluating, and protecting your system even easier and more efficient.
New functions (requiring a DP-USB Gateway and an INT69 protection relay capable of diagnosis or an INT280 oil level regulator):
• You can upload data directly to the system via USB cable. This provides access to the error memory/counter so you can assess the current status of the system and review the operating data.
• You can create a report in PDF format in no time at all and forward it directly to the customer if necessary.
• You can upload collected data to the free KRIWAN Diagnosis web service (Internet INTelligence). This backs up and archives the data, which can then be called up at anytime and anywhere via the Internet.
Additional functions (not requiring a DP-USB Gateway):
• You can retrieve data sheets for installed KRIWAN products so that they are available quickly and paper-free for maintenance and repair work on the system. Simply scan a product's data matrix code using a smartphone camera, or enter the part number.
• You can analyze the status of the compressor using the LED blink code, which is read using a smartphone camera and interpreted by the app.
Lembre-se: a escolha de potência correta significa um ambiente refrigerado na temperatura ideal, além de uma boa economia de energia.
