  • (1888PressRelease) February 08, 2015 - In the second half of 2014 Encole LLC has seen an increase in demand for it's high-pressure sight glasses from the plant oil extraction industry.

    These particular sight glasses are chemically inert in the oil extraction process and can hold the high pressure of the carbon-dioxide type extractors. Both, CO2-based systems and butane-based systems benefit from the Encole sight glasses because of their regulatory compliance at high pressure operations. These sight windows have been tested in accordance with the Pressure Equipment Directive for vessels exceeding 10-litter volumes. The sight glass housings are made from AISI 316 Stainless Steel with GE-124 quartz windows bonded to the housings with FDA-approved quartz-based fill. The sight windows fully pass the rigorous FDA CFR 175.300 Food Grade Testing Requirement. The advantage of these Encole sight glasses is the excellent optical clarity not available in fused type sight glasses, and also food grade compliance not available from gasketed sight glasses with elastomer seals. Encole sight glasses allow non-distorted viewing of the process behind the window, while retaining the high-pressure and high temperature performance and corrosion resistance. Particular interest in these sight glasses has been seen from the hemp oil extractors possibly due to deregulation of the medical use of marijuana.

    High pressure sight glasses have the following technical parameters:
    • Operating Pressure: up to 7,040 psi, internal pressure, 580 psi external pressure,
    • Operating Temperature: -60 oC to +220oC
    • Available in NPT-threaded configuration, Sizes 1" to 2" in 1/2" increments. Custom sizes and flanged configurations are available by custom order.
