HANNING & KAHL point machines have been operated with Pentopol J32 hydraulic oil for many years. The particular product properties of Pentopol J32 were the reason why only this oil was approved for use in our products.

Fuchs Schmierstoffe, the company which owns the Pentopol brand, discontinued production of Pentopol J32 hydraulic oil in 2022 because one additive was no longer available and provided a product with comparable properties: Renolin ZAF 32 BHV.

Prior to qualification and approval of the new hydraulic oil, HANNING & KAHL conducted diverse intensive tests:

• Media stability (seals, surfaces)
• Lubrication properties (component wear)
• Operational suitability (wear, temperature behaviour)

The new hydraulic oil has been approved as an operating medium for our point machines. Renolin ZAF 32 BHV and Pentopol J32 can be mixed in any ratio. Existing stocks may be used up, approval for Pentopol J32 remains unchanged. No measures are necessary for first use of Renolin ZAF 32 BHV.

Discontinuation hydraulic oil for HANNING & KAHL point machines.

We are informing you that HANNING & KAHL is ceasing production of HN-P Diagnosis 7 (K1089589) and earlier versions as of now. As a product alternative, we propose HuK-SSP Version 8.01 (K1125676).

HANNING & KAHL ceased production of the HN-P Diagnosis 7 and earlier versions on account of lack of compatibility with Windows11.

HANNING & KAHL is of course aware of its commitment as system supplier of complete control and safety systems and continues to serve the aftermarket. The diagnostic programs (Version 7 and earlier) available up to now can still be used with older Windows versions (Windows10 and earlier).

If you would like individual advice, please do get in touch.

Following discontinuation of hydraulic oil Pentopol J32, we informed you in August 2022 that preliminary approval had been granted for Mabanol Hyd J32 supplied by Mabanol as of 01.08.2022 as well as for successor Renolin ZAF 32 BHV.

Final approval for Mabanol Hyd J32 has been available since 01.03.2023.

HANNING & KAHL performed various intensive tests for approval and qualification of the new hydraulic oil:

Tests for media resistance (seals, surfaces)

Tests for examination of lubrication qualities (wear of components)

Tests for fitness for purpose (wear and temperature behaviour)

Pentopol J32, Mabanol Hyd J32 and Renolin ZAF 32 BHV can be mixed in any ratio. Existing stocks can still be used up, there is no change to approval for Pentopol J32. No special measures are necessary the first time Mabanol Hyd J32 is used. It is not necessary to flush or clean the equipment outside of the normal maintenance intervals.

Please refer to the current HANNING & KAHL operating manual for the oil purities required for safe operation of the braking systems.

We would like to point out that if the oils are mixed, oil analysis of the mixture can no longer be assessed.

The oil which is colourless by nature is coloured yellow.

Your HANNING & KAHL contacts will be happy to answer any questions you may have.

HANNING & KAHL is discontinuing the production of the above mentioned MVB card due to obsolescence.

Of course, HANNING & KAHL is aware of its obligation as a system supplier of complete electrohydraulic brake systems to continue to serve the after sales market.

The existing MVB card can be replaced by a successor EIB board (Ethernet Interface Board) with an extended range of functions. For the correct function of the new EIB board, a one-time project-specific modification of the software is necessary. The EIB board replaces the MVB card, and the interface board (BIS or CIB) required for control.

The basis for this modification is a previous upgrade of CPU1 to CPU2. This obsolescence was already announced in 2006.

If the upgrade from CPU1 to CPU2 has not yet taken place, it can be implemented at the same time.

Please contact Mr. Tietz (-668) or Mr. Davies (-8162) if you need further information.

HANNING & KAHL inform you that the production of the above-mentioned speed sensor due to obsolescence. Of course, HANNING & KAHL is aware of its obligation as a system supplier of complete electrohydraulic brake systems to continue to serve serial deliveries and the after sales market.

The existing speed sensors can be replaced by a follow-up product with the same range of functions. It is not possible to place a last order for the above-mentioned part numbers. For orders already confirmed, the successor product will be delivered.

HANNING & KAHL braking systems and hydraulically activated point machines have been operated with Pentopol J32 hydraulic oil for many years. The particular product properties of Pentopol J32 were the reason why only this hydraulic oil was approved by HANNING & KAHL for use in our products.

Fuchs Schmierstoffe GmbH, the company which owns the brand Pentopol, has announced that they will be discontinuing production of hydraulic oil Pentopol J32 in Q1 2022 as one additive is no longer available. Parallel to this, Fuchs Schmierstoffe has presented a product with comparable properties.

Fuchs Schmierstoffe’s new hydraulic oil is called Renolin ZAF 32 BHV.

From 01 December 2021, Renolin ZAF 32 BHV hydraulic oil is approved for use as an operating medium for our braking systems and point machines.

Prior to granting qualification and approval of the new hydraulic oil, HANNING & KAHL carried out diverse intensive tests:

• Tests for media stability (seals, surfaces)
• Tests for examination of the lubrication properties (wear of components)
• Tests for operational suitability (wear and temperature behaviour)

Renolin ZAF 32 BHV and Pentopol J32 can be mixed in any ratio. Existing stocks may be used up, approval for Pentopol J32 remains unchanged. No particular measures are necessary for first use of Renolin ZAF 32 BHV. It is not necessary to flush or clean the equipment outside of the normal maintenance intervals.

However, we would like to point out that if the oils are mixed, an oil analysis of the mixture can no longer be unambiguously assessed.

Renolin ZAF 32 BHV which is also naturally almost colourless is also yellow coloured.

In addition, HANNING & KAHL is currently working on approval of a second alternative to Pentopol J32. Corresponding tests are ongoing prior to approval and qualification. Approval of this alternative is to be expected mid 2022.

Your account managers and clerks would be happy to answer any questions you may have.

Announcement about Obsolescence Proportional Pressure Control Valves
The following HANNING & KAHL Material numbers are affected:
40112 (SAP No. K1003242) and 40117 (SAP No. K1003246)

We hereby inform you that HANNING & KAHL will discontinue the delivery for above mentioned valves due to obsolescence.

Of course, we are aware of our obligation as a system supplier of complete electrohydraulic brake systems. We will continue to serve the after-sales market. In the future, there will be a further developed successor product that is functionally and installation compatible.

Due to the age of the affected units, there will be individual solutions for this. It is therefore necessary to assess in each individual case to what extent adaptations to the hardware as well as the software will have to be made.

Please call Mr Tietz +49 5202 707-668 or Mr Davies +49 5202 707-8162 if you need further information.
