Helios Energy Efficient Falling Film Evaporator

With BCT’s experience in the cannabis and hemp industry, and taking a look at what is on the market today, we have developed the most energy-efficient falling film evaporator system. Boulder Creek Technology patent-pending Helios incorporates new technology into the established falling film process that allows energy savings of up to 65% compared to a conventional system.

Conventional falling film systems work in a thermal open loop, requiring an external heat source to boil solvent and a chiller to condense that solvent, using energy in both steps. BCT’s Helios uses a heat pump to recycle the energy from the condenser back to the evaporator, closing the heat loop and dramatically reducing energy use by 65%.

Helios, like other falling film systems, pumps your extracted oil-solvent solution into the evaporator at a precise rate where it is rapidly heated causing the solvent to be boiled and the oil recovered. Unlike other falling film systems, BCT’s system only heats your oil up to 55C, improving oil quality and terpene retention compared to other systems that need to heat the oil to higher temperatures.

After the solvent is boiled in the evaporator, it passes through Helios' cyclone separator where entrained oil carryover is separated from the solvent vapor. The oil-free solvent vapor then flows to the condenser to be reliquified, where its latent heat is captured by the heat pump and returned to the evaporator.

Boulder Creek Technology’s falling film system also incorporates technology that allows you to control and monitor the system locally over wifi, or at a remote location over the internet.  Remote access also allows us to seamlessly resolve problems you may encounter over the internet with your permission, and to assist with diagnostics and troubleshooting to minimize downtime.
