New GBC 90 bar Ball Valves Released to Market

Image showing three Danfoss ball valves: two older models and one new GBC 90 bar model.

Danfoss is introducing a new GBC 90 bar ball valve design for CO2 applications. Production of the new GBC 90 bar has begun and the product is released. This new design will replace the GBC 45 bar and GBCH 90 bar for CO2. They feature stainless steel as the primary base material, providing customers with enhanced performance and reliability. The new models are similar in dimensions and connections to the GBCH, making them an exact drop-in replacement for former models in existing system designs. The new range is extended with solder connections up to 1 5/8 in. (42 mm) to fit more market needs. New code numbers will be created for this range.

The existing CO2 GBC 45 bar and GBCH 90 bar will be phased out.

Launch Plan:

The new GBC 90 bar will be released in two waves:

1st wave covers size 6s to 16s, release planned in Jan. 2024.
2nd wave covers size 18s to 42s, release planned in Jul. 2024.

The old CO2 GBC 45 bar and GBCH 90 bar will be available for order until March 31st, 2024, for the first wave and until the end of August for the second wave.

QR Code for Optyma™ Package Condensing Units

Image showing a Danfoss Optyma package condensing unit with a sticker featuring a QR code and instructions to scan for technical documents.

As part of the continuous improvement of our products, we will now be implementing a QR product finder code sticker on all our Optyma package condensing units.

Customer Impact

Better access to all local language documentation from the customer's mobile phone.

Implementation date

All products will get this sticker on week 04 / 2024 for all package units beginning from serial number 06411CG0424, but the functionality in Ref Tool App is already available: Product Finder (danfoss.com)

Labelling will be sticked on an easily accessible place.
The QR code is giving access to Ref Tools App product search.
You only need to add the 114X____ code to reach out to all local language documentation, instruction guideline, piping, wiring etc... Product Finder (danfoss.com)

Change in Brightness of ERC 11X Blue LED Variants

There has been a change in blue LED chip and a component supplier change. So, there is a change in brightness on all ERC 11X variants (ERC 111A, 112C, 112D & RDI 107A) blue LED versions.

This modification is aiming to overcome end of life of existing blue LED chip, and we are replacing it with a new blue LED chip. There is also a change of component supplier because of above reason.

To overcome the possible stop in production due to end-of-life components, Danfoss has evaluated, tested, and approved new blue LED to be used in ERC 11X. There is a change in the brightness of the LED, which is much brighter than the current one. It is not a change in product code and function.

Technical difference current/new blue LED chip

Before	After
Luminous Intensity: min. 20, max. 30 mcd	Luminous Intensity: min. 30, max. 45 mcd

Image showing two displays side-by-side. The left display shows 'EO 1.601.0' with a label 'Existing blue shade'. The right display shows a similar display with a label 'New blue shade'.

Please Note:

ERC has a feature where in you can adjust display intensity through a parameter din. din - Display Intensity. The controller can have its display intensity (brightness) set in one of two ways:

A) With a Danfoss ambient light sensor attached, the brightness of the display is adjusted automatically according to the ambient light level (see the assignments section in the user guide).
B) When no ambient light sensor is attached, the display intensity can be set to a fixed intensity.

Both options are on a scale of 1 to 10, where 10 is the brightest. din was set at 10 in ERC at the time of testing on both old and new blue chip.

Affected products

ERC 11X variants (ERC 111A, 112C, 112D & RDI 107A) blue LED versions.

AK-PC 772B and AK-PC 781B Pack Controllers: New Product Versions

Image showing two Danfoss AK-PC 772B and AK-PC 781B pack controllers.

New product versions of the AK-PC 772A and AK-PC 781A named respectively as AK-PC 772B and AK-PC 781B are now available, with the intention to support communication over IP towards AK-SM 800A series and overcome component scarcity of the LON chip for the existing AK-PC 772A and AK-PC 781A.

The new products are:

AK-PC 772B, 080Z0195
AK-PC 781B, 080Z0194

AK-PC 772B with SW rel. 1.5 will present the same features and functionalities of the existing AK-PC 772A with SW rel. 1.3, with the only difference of having communication over IP towards AK-SM 800A series and the support of Bock compressors.

AK-PC 781B with SW rel. 2.5 will present the same features and functionalities of the existing AK-PC 781A with SW rel. 2.31, with the only difference of having communication over IP towards AK-SM 800A series and the support of Bock compressors.

The AK-PC 722B is compatible with SW rel. 1.5 and onwards. The AK-PC 781B is compatible with SW rel. 2.5 and onwards. Note that these new devices are NOT compatible for use with software releases prior to the one implemented from the factory. Incorrect software download can permanently damage the device.

You should expect to have to set up a new network configuration for communication between the AK-PC 772B and AK-PC 781B towards the AK-SM 800A System Manager. In the network configuration they will need to use a DHCP router for Pack IP addressing.

Network Configuration Example

Diagram shows a network setup with a System Manager (AK-SM 800A) connected via Ethernet 0 (UDP/IP) to a DHCP router. The router is connected to LAN. Two Pack controllers (AK-PC 7xxB) are shown connected to the LAN, one with address 011 and another with address 012. An AK-XM device is also connected to the LAN. A 'Remote Connection' is also indicated.

The new AK-PC 772B and AK-PC 781B will be available in stock for sale from week 04/2024.

If you have any questions regarding this information, please contact your local Danfoss sales representative.
