Castrol Alpha VT 32 Turbo transmission oil
Castrol Alpha™ VT 32 has been developed specifically for Voith Turbo transmissions to provide long service life and realibility, and to exceed the Voith specification 3.90-8e_2011-07
Castrol Alpha VT 32 is formulated for hydrokinetic transmissions used mainly in railway locomotives. Other applications include trucks and heavy off-highway equipment incorporating this type of transmission unit. The oil is also suitable for conventional industrial gearboxes where a low-viscosity oil is suitable. This oil provides higher load-carrying performance, together with excellent oxidation resistance, anti-corrosion and minimal foaming.
Alpha VT 32 is fully compatible with nitrile, silicone and fluropolymer seal materials.
Castrol Alpha VT 32 meets the requirements of:
Voith Turbo Specification 3.90-8e_2011-07
- Long service life
- Excellent load carrying and micropitting resistance
- Good seal compatibility
- Low foam and rapid air release
- Excellent demulsification

The product should not be stored at temperatures over 60°C. It should be kept away from sunlight, intense cold and extreme temperature fluctuations. If possible, the packaging should not be exposed to the elements. Otherwise, the drums should be laid horizontally to avoid any contamination from water and to prevent the product’s label from rubbing off.
