DSH large scroll compressors available with factory-mounted oil level switch
Selected models in the DSH large scroll compressor range are now available with a factory-mounted oil level switch (OLS). This is an important enhancement to our DSH large scroll compressor range. The OLS provides real-time monitoring of oil level and oil temperature to support compressor protection and system reliability.
Main advantages
- Proactive protection: Early detection of low-oil conditions before reaching critical levels.
- Enhanced reliability: Reduced risk of compressor damage and downtime.
- Advanced diagnostics: Integrated NTC sensor measures oil temperature, enabling oil superheat calculation and interpretation of dilution curves from Danfoss guidelines to assess lubrication quality.
New commercial references
How it works
The OLS is a float-type sensor with a potential-free reed contact that changes state depending on the oil level in the compressor sump. The alert level is set just below the oil sight glass. This is not the critical lubrication level, but an indication that the oil has left the “comfort zone” and that action is required.
This provides a defined reaction time before a dangerous threshold is reached.
See Recommended protection logic below.
When the oil level drops below the alert threshold, the reed contact opens and sends a signal to the controller. The integrated NTC sensor measures oil temperature accurately, which is essential for calculating oil superheat - a key input for interpreting the dilution curves provided in Danfoss guidelines.
This helps assess lubrication quality and detect possible refrigerant dilution in the oil.
Important note
OLS operation may be disrupted if ferromagnetic particles are present in the refrigeration circuit. Ensuring circuit cleanliness is critical to guarantee optimal OLS functionality.
It is not possible to install the OLS on standard DSH compressors, as this requires a new shell design for PED compliance. Therefore, when the OLS is required, it must be ordered pre-mounted from the factory.
Recommended protection logic
- Within 5 minutes after an event (start-up, defrost, etc.): If the low-oil signal is continuous for more than 5 seconds, stop the compressor immediately.
- Under stable conditions (more than 5 minutes after the last event): Attempt to restore oil level within 120 seconds; if unsuccessful, stop the compressor.

Flexible grommets become standard for SH compressors (SH180–380)
An update is being implemented to the standard accessories supplied with the Danfoss SH large scroll compressor range (models SH180 to SH380). Based on current market application requirements, these compressors will be supplied with flexible mounting grommets as standard.
Effective from the second quarter of 2026 (Q2 2026), all compressors in this range will be factory-supplied with flexible mounting grommets 8156138 instead of the current rigid mounts.
This change reflects the current shift in market applications. Most compressors in this range are now installed in single-unit applications, where flexible grommets are required for effective vibration and noise damping. Supplying flexible grommets as standard removes the need for most customers to order a separate accessory kit and reduces disposal of unused rigid parts.
We are confident that this update will streamline your installation process and support our shared environmental goals.
What this means for you
- For single-compressor applications: You will no longer need to order a separate accessory kit. The correct flexible mounts will be included directly with the compressor, ready for installation.
- For parallel (manifold) applications: If your installation does not allow the compressors to be mounted directly onto the rails, you will now need to order the rigid mounting kit separately.The part number for Mounting Compressor kit is 120Z0495.

AK-SM 800A Series software release 5.0, including SvW update
Software release 5.0 is now available for the ADAP-KOOL™ System Manager 800A series.
This release is accompanied by Danux package 4.14.017.194, which is recommended to be installed before loading the AK-SM800A application update.
Both packages are available on ADAP-KOOL support site
Software package 5.0 requires Danux 4.14.017.194
Important notes on package 5.0 update
Please note that release R5.0.x includes important changes to the overall database structure. As a result, returning to an earlier software version after the update will not be supported. To ensure a smooth update process, we strongly recommend taking a full backup of the system database before starting the upgrade.
As part of the update, existing History data will be automatically converted to the new format. The progress of this process can be followed under [History Config --> Status]. To help protect the data during conversion, we recommend avoiding unit resets while this process is running. The system can tolerate up to three resets during conversion; however, if a fourth reset occurs, any history data not yet converted will be lost.
After the update, StoreView Web (SvW) embedded will become the default remote user interface. SvB5 will remain available for a limited period and is planned to be phased out in a future release.
Main release highlights
Release 5.0.x is a major release for the SM800A series and is recommended for all customers.
Multiple updates and new features are included. Some of the main highlights are:
- Default remote user interface now StoreView Web (SvW ’embedded’)
- Increased capacity for EDF files (from 1500 to 3000)
- Improved history function and memory management
- Support for Alsmart Modbus/TCP
- New caution prompts added when removing key application config (local screen only)
- Improved SNMP performance
- Security updates
- Bug fixes
StoreView Web (embedded user interface - new)
The term SvW Embedded refers to the remote user interface (web screens) integrated directly into the System Manager. Following the update to R5.0.x, users can enter the IP address or URL of the System Manager into a standard web browser to access the interface. Instead of SvB5, the system will then open StoreView Web (SvW). SvW is the preferred remote user interface going forward and complements the already available SvW Cloud and SvW desktop solutions.
- SvW comes in three variants
o SvW ‘Cloud’ (requires internet connection)
o SvW ‘Embedded’ – built into the System Manager (no internet required)
o SvW Desktop – SvW for your PC (used to connect to http and https units) - SvW cloud can be accessed via https://svw.danfoss.com and can be used in conjunction with HTTPS enabled 800A units
- To download SvWDesktop (supporting http/https 800A units) first log into the cloud version https://svw.danfoss.com, then via the ‘More…’ tab, you can download the desktop version.
Updated History function
The History function has been updated to improve system management of the data and to assign dedicated flash memory for new Active and Archive directories. Improvements include:
- Strict boundary protection – memory allocation can no longer be overfilled
- Dedicated assigned memory allocation for new Database Directories
- New Active Database Directory for polled points (8GB)
- New Archive Database Directory (2GB)
- History is stored as monthly files within the Active directory until either capacity is reached or the start of a new month – then last file will be automatically transferred to the Archive directory – this ensures the Active directory cannot overspill / delete data / freeze system
- History in Active directory can always be viewed via the History view screen
- History migrating to Archive directory will be converted to CSV and zipped to minimize size and maximize the length of time it can be stored (2GB). Any transitioned monthly file in Archive can be downloaded
- The maximum number of polled points is updated to 3000*
*it may not be possible to log 3000 points at max frequency (1 min) on slow field bus (i.e. Serial Modbus) – in this case the sample rates can be increased - Conversion from current history architecture to the new format is done automatically and starts after the system has been updated to version 5.0.x software
Important changes
For security reasons, the service tool (ST-500) port is disabled by default. To enable a remote service tool tunnel connection, enable the port via the [Configuration > Security screen]. Disable the port again when the tunnel is no longer needed. To comply with Cyber Security requirements, new user accounts must have strong passwords (8 characters, including 1 uppercase, digit, and special character).
