<p>A vaporizer having a pair of heat exchanger blocks (14) each with a vaporization tube formed therein. The heat exchanger blocks are in face-to-face arrangement and the vaporizer tubes (18) are coupled together in series. A plurality of positive temperature coefficient (PTC) (16) heating elements are clamped in position between the heat exchanger blocks to provide the heat for vaporization of the liquefied gas. A capacity control valve controls the flow of liquefied gas into the vaporizer tubes.</p> |
