Energy harvesting thermoelectrics uncrated by Marlow Industries

September 27, 2011 – Marketwire — Thermoelectric maker Marlow Industries launched the EverGen series, thermoelectric-based energy harvesting devices offering low-cost, zero-maintenance power for wireless sensor applications. Wired systems or batteries for wireless sensors prove costly and time-consuming to maintain.

The devices convert small temperature differences (degrees) into milliwatts of power. This electricity is enough to power wireless sensors for the application’s lifetime. The solid-state energy source can be used with sensors, valve solenoids, actuators, and other small devices. The current line includes three designs, with additional products in the works.

EverGen thermoelectric devices:
EverGen Liquid-to-Air: Higher temperature fluid stream and ambient air. Energy harvested via natural convection.
EverGen Liquid-to-Liquid: Higher temperature fluid stream and lower temperature fluid stream.
EverGen Solid-to-Air: Higher temperature solid surface and ambient air. Energy harvested via natural convection.

Marlow will work with customers in multiple industries to integrate energy harvesting devices into existing wireless sensor applications and currently wired installations. Customers need wireless energy harvesters for existing and new builds, the company notes.

New building codes require lighting and heating, ventilation and air-conditioning (HVAC) "smart" designs that moderate usage. Recycling waste heat into electrical power is one way to achieve this, according to Marlow Industries. The company’s aim is to turn the "emerging alternative energy market" into the "mainstream," said Barry Nickerson, general manager, Marlow Industries.

Marlow Industries, a subsidiary of II-VI incorporated, develops and makes thermoelectric technology including thermoelectric modules (TEMs) and subsystems for the aerospace, defense, medical, commercial, industrial, automotive, consumer gaming, telecommunications and power generation markets.
