Turbine Oil or Heat-Transfer Fluid? Write the Purchase Request Clearly

Start by naming the system and the fluid's job. A turbine lubrication circuit and a heat-transfer circuit are different purchase requests even when both appear under industrial fluids. Record the equipment manufacturer, model or asset number, service description and the exact instruction from the current equipment manual. If the site also has a separate circulation-oil system, list it on its own line instead of combining it with the turbine or heat-transfer requirement.

For a turbine-oil request, copy the required viscosity grade and any named standard or approval from the OEM document. The ALFA catalogue records TurbineCore 32, 46 and 68 as separate request targets with target viscosities ISO VG 32, 46 and 68. Those catalogue entries identify the requested line only; they do not prove interchangeability, OEM approval, operating-temperature suitability or availability for a particular machine. One grade should be tied to one identified equipment requirement.

For heat-transfer service, do not select a fluid from the turbine-oil list. Record the system type, operating and maximum temperatures stated by the site engineer or equipment document, heater or process reference, construction materials, current fluid if known, estimated system volume and whether the work is a new fill, top-up or replacement. ALFA ThermoCore is recorded as a heat-transfer fluid line, but dilution, temperature range and material compatibility must come from the controlled technical document for the offered formulation.

Keep quantity and packaging separate from the technical selection. The catalogue request groups for TurbineCore and ThermoCore include 10 L or 20 L containers, 200 L or 208 L drums, and a nominal 1,000 L IBC option whose actual net fill must come from supplier data. State the preferred pack, unit count, total required volume, delivery country and city or port, receiving site, currency and requested delivery date.

Before approval, ask for the current TDS and SDS and any OEM approval specifically required by the equipment record. The quotation should identify the confirmed product, pack, quantity, currency, delivery scope, document availability and validity period. Technical review should compare the offered formulation with the original equipment or process requirement before acceptance, mixing or payment. A familiar brand name or matching viscosity number alone is not a compatibility decision.
