INTRODUCTION
The LIMNION LIMA-1 combines high performance and compact size in a geothermal transfer system designed for installation in lakes, ponds and rivers. The LIMA-1 is engineered to extract or reject energy from and to the earth using surrounding water (fresh or salt) as the transfer medium. Unlike conventional field built lake loops or mats, the LIMA-1 is engineered and manufactured using fluoropolymer tubing in a modern and strictly controlled facility. The LIMA-1 features a number of break-through innovations (Patents Pending) in geothermal energy transfer and an industry leading heat exchanger design.

INNOVATION
The Core of the LIMA-1 is an innovative energy exchanger that has been engineered for optimum efficiency while maintaining a compact size of approximately 1 meter (3 feet) in diameter.

More than 800 meters (2625 feet) of fluoropolymer tubing are carefully positioned and spiralled in the LIMA-1. A combination of low flow resistance and high thermal transfer characteristics deliver balanced and unequalled heat exchanger performance.

The product of extensive research and development, the LIMA-1 incorporates numerous features that address growing concerns pertaining to the environmental impact associated with traditional submerged loops and mats. Once installed, the LIMA-1 is firmly anchored on the lake bottom and offers a safe recluse for fish fingerlings and other aquatic life.

Every consideration has been made to ensure ease of handling and installation. The LIMA-1 is remarkably small, light-weight and rugged. Smooth edges, integrated hand-holds, commercial grade header pipes and pipe fittings will consistently exceed the expectations of the installer by reducing labour costs and making the installation straight forward and trouble-free.

APPLICATION

Anchor Ball Approx. 30.5 cm (12 inch) Diameter Foot Print

The LIMA-1 is designed to enhance the operation of any good quality geothermal heat pump*.
A single LIMA-1 geothermal transfer system will provide up to 72,000 Btu of energy exchange. Additional LIMA-1 systems may be combined to meet virtually any thermal transfer requirement. The LIMA-1 is suitable for installation in any body of water**.

The small foot print and modest size of the LIMA-1 renders it virtually invisible from the surface and ensures minimal impact on the sensitive lake bottom.

* * sized according to heating/cooling load. Recommend a minimum of 1.2-1.8 Meters (4-6 feet) of water depth above the LIMA-1.

CONSTRUCTION & OPERATION
The LIMA-1 is constructed using quality grade High Density Polyethylene and Fluoropolymers. The exchanger pipes are constructed from an enhanced fluoropolymer which reduces resistance to flow and increases thermal transfer. The LIMA-1 is professionally constructed in a state of the art manufacturing and testing environment ensuring quality, performance, reliability and durability. The superior flow and transfer rates of the LIMA-1 are compatible with readily available heat exchange fluids. LIMNION encourages the use of non-toxic Propylene Glycol exchange fluids. A complete LIMA-1 installation contains significantly less heat exchange fluid than a convention loop or mat installations (Typically 50% less).

The LIMA-1 is shipped with all components for water installation. LIMNION offers a line of high quality accessories and recommends the low temperature, non-crush, header pipes for installation from the LIMA-1 to shore (Fittings for connection to HDPE pipe provided). The PVC, non- floating header pipes have a built in helix for strength and durability and are available in lengths up to 30.48 meters/100 feet. The LIMA-1 can be unpackaged, assembled and installed in less than 1 hour.
